     ops - Perl pragma to restrict unsafe operations when compil-


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

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


     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 safety.
