lib:ops

See the current Perl documentation for lib:ops.

Here is our local, out-dated (pre-5.6) version:


ops - Perl pragma to restrict unsafe operations when compiling



  perl -Mops=:default ...    # only allow reasonably safe operations

  perl -M-ops=system ...     # disable the 'system' opcode



Since the ops pragma currently has an irreversable 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 safety.
