ops - Perl pragma to restrict unsafe operations when compiling

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.
