ops - Perl pragma to restrict unsafe operations when compiling
perl -Mops=:default ... # only allow reasonably safe operationsperl -M-ops=system ... # disable the 'system' opcodeSince theops pragma currently has an irreversible global effect, it is only of significant practical use with the-M option on the command line.
See theOpcode module for information about opcodes, optags, opmasks and important information about safety.
