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