 ops - Perl pragma to restrict unsafe operations when compiling

SSYYNNOOPPSSIISS #

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

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

DDEESSCCRRIIPPTTIIOONN #

 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.
