=head1 NAME
ops - Perl pragma to restrict unsafe operations when compiling
=head1 SYNOPSIS
perl -Mops=:default ... # only allow reasonably safe operations
perl -M-ops=system ... # disable the 'system' opcode
=head1 DESCRIPTION
Since the C<ops> pragma currently has an irreversible global effect, it is
only of significant practical use with the C<-M> option on the command line.
See the L<Opcode> module for information about opcodes, optags, opmasks
and important information about safety.
