B - The Perl Compiler Backend
The "B" module supplies classes which allow a Perl program to delve into its own innards. It is the module used to implement the "backends" of the Perl compiler. Usage of the compiler does not require knowledge of this module: see the O module for th...

O - Generic interface to Perl Compiler backends
This is the module that is used as a frontend to the Perl Compiler. If you pass the "-q" option to the module, then the STDOUT filehandle will be redirected into the variable $O::BEGIN_output during compilation. This has the effect that any output pr...

re - Perl pragma to alter regular expression behaviour
'taint' mode When "use re 'taint'" is in effect, and a tainted string is the target of a regexp, the regexp memories (or values returned by the m// operator in list context) are tainted. This feature is useful when regexp operations on tainted data a...

DB - programmatic interface to the Perl debugging API
Perl debug information is frequently required not just by debuggers, but also by modules that need some "special" information to do their job properly, like profilers. This module abstracts and provides all of the hooks into Perl internal debugging f...

mro - Method Resolution Order
The "mro" namespace provides several utilities for dealing with method resolution order and method caching in general. These interfaces are only available in Perl 5.9.5 and higher. See MRO::Compat on CPAN for a mostly forwards compatible implementati...

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...

subs - Perl pragma to predeclare subroutine names
This will predeclare all the subroutines whose names are in the list, allowing you to use them without parentheses (as list operators) even before they're declared. Unlike pragmas that affect the $^H hints variable, the "use vars" and "use subs" decl...

Historically the "sort" pragma you can control the behaviour of the builtin "sort()" function. Prior to v5.28.0 there were two other options: use sort '_mergesort'; use sort '_qsort'; # or '_quicksort' If you try and specify either of these in v5.28+...

utf8 - Perl pragma to enable/disable UTF-8 (or UTF-EBCDIC) in source code
The "use utf8" pragma tells the Perl parser to allow UTF-8 in the program text in the current lexical scope. The "no utf8" pragma tells Perl to switch back to treating the source text as literal bytes in the current lexical scope. (On EBCDIC platform...

open - perl pragma to set default PerlIO layers for input and output
Full-fledged support for I/O layers is now implemented provided Perl is configured to use PerlIO as its IO system (which has been the default since 5.8, and the only supported configuration since 5.16). The "open" pragma serves as one of the interfac...

less - perl pragma to request less of something
This is a user-pragma. If you're very lucky some code you're using will know that you asked for less CPU usage or ram or fat or... we just can't know. Consult your documentation on everything you're currently using. For general suggestions, try reque...

vars - Perl pragma to predeclare global variable names
NOTE: For use with variables in the current package for a single scope, the functionality provided by this pragma has been superseded by "our" declarations, available in Perl v5.6.0 or later, and use of this pragma is discouraged. See "our" in perlfu...
