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.
