ops - Perl pragma to restrict unsafe operations when compiling
Since the "ops" pragma currently has an irreversible global effect, it is only of significant practical use with the "-M" option on the command line. See the Opcode module for information about opcodes, optags, opmasks and important information about...

B::Terse - Walk Perl syntax tree, printing terse info about ops
This module prints the contents of the parse tree, but without as much information as CPAN module B::Debug. For comparison, "print "Hello, world."" produced 96 lines of output from B::Debug, but only 6 from B::Terse. This module is useful for people ...

Opcode - Disable named opcodes when compiling perl code
Perl code is always compiled into an internal format before execution. Evaluating perl code (e.g. via "eval" or "do 'file'") causes the code to be compiled into an internal format and then, provided there was no error in the compilation, executed. Th...

perlop - Perl operators and precedence
In Perl, the operator determines what operation is performed, independent of the type of the operands. For example "$x + $y" is always a numeric addition, and if $x or $y do not contain numbers, an attempt is made to convert them to numbers first. Th...
