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 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.
