perl-Opcode - Disable named opcodes when compiling perl code
- Description:
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.
The internal format is based on many distinct opcodes.
By default no opmask is in effect and any code can be compiled.
The Opcode module allow you to define an operator mask to be in
effect when perl next compiles any code. Attempting to compile code
which contains a masked opcode will cause the compilation to fail
with an error. The code will not be executed.
