Symbols starting with "_" no longer forced into main,
Double-colon valid package separator in variable name,
2nd and 3rd args to splice() are now in scalar context,
Can't do goto into a block that is optimized away,
Can't use whitespace as variable name or quote delimiter,
while/if BLOCK BLOCK gone,
** binds tighter than unary minus,
foreach changed when iterating over a list,
split with no args behavior changed,
-e behavior fixed,
push returns number of elements in resulting list,
Some error messages differ,
split() honors subroutine args,
Bugs removed
Space between .
and = triggers syntax error,
Better parsing in perl 5,
Function parsing,
String interpolation of $#array differs,
Perl guesses on map,
grep followed by { if it starts BLOCK or hash ref
Formatted output and significant digits, Auto-increment operator over signed int limit deleted, Assignment of return values from numeric equality tests doesn't work, Bitwise string ops
Negative array subscripts now count from the end of array,
Setting $#array lower now discards array elements,
Hashes get defined before use,
Glob assignment from localized variable to variable,
Assigning undef to glob,
Changes in unary negation (of strings),
Modifying of constants prohibited,
defined $var behavior changed,
Variable Suicide
Elements of argument lists for formats evaluated in list context,
caller() returns false value in scalar context if no caller present,
Comma operator in scalar context gives scalar context to args,
sprintf() prototyped as ($;@)
LHS vs.
RHS of any assignment operator,
Semantic errors introduced due to precedence,
Precedence of assignment operators same as the precedence of assignment,
open requires parentheses around filehandle,
$: precedence over $:: gone,
Precedence of file test operators documented,
keys,
each,
values are regular named unary operators
s'$lhs'$rhs' interpolates on either side,
m//g attaches its state to the searched string,
m//o used within an anonymous sub,
$+ isn't set to whole match,
Substitution now returns null string if it fails,
s`lhs`rhs` is now a normal substitution,
Stricter parsing of variables in regular expressions,
m?x? matches only once,
Failed matches don't reset the match variables
Barewords that used to look like strings look like subroutine calls,
Reverse is no longer allowed as the name of a sort subroutine,
warn() won't let you specify a filehandle
SysV resets signal handler correctly,
SysV seek() appends correctly
@ always interpolates an array in double-quotish strings,
Double-quoted strings may no longer end with an unescaped $,
Arbitrary expressions are evaluated inside braces within double quotes,
$$x now tries to dereference $x,
Creation of hashes on the fly with eval "EXPR" requires protection,
Bugs in earlier perl versions,
Array and hash brackets during interpolation,
Interpolation of \$$foo{bar},
qq() string passed to eval will not find string terminator
Perl5 must have been linked with same dbm/ndbm as the default for dbmopen(),
DBM exceeding limit on the key/value size will cause perl5 to exit immediately
require/do trap using returned value,
split on empty string with LIMIT specified

There must be no space after the << part, There (probably) should be a semicolon at the end, You can't (easily) have any space in front of the tag

Does concept match the general goals of Perl?, Where is the implementation?, Backwards compatibility, Could it be a module instead?, Is the feature generic enough?, Does it potentially introduce new bugs?, Does it preclude other desirable features?, Is the implementation robust?, Is the implementation generic enough to be portable?, Is the implementation tested?, Is there enough documentation?, Is there another way to do it?, Does it create too much work?, Patches speak louder than words
rsync'ing the source tree, Using rsync over the LAN, Using pushing over the NFS, rsync'ing the patches
It's easier to rsync the source tree, It's more reliable
It's easier to rsync the patches, It's a good reference, Finding a start point, Finding how to fix a bug, Finding the source of misbehaviour
