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...

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...

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...
