NAME
       ops - Perl pragma to restrict unsafe operations when
       compiling

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

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


DESCRIPTION
       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 the Opcode manpage module for information about
       opcodes, optags, opmasks and important information about
       safety.
