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.
