NAME

6       ops - Perl pragma to restrict unsafe operations when compiling
7

SYNOPSIS

9         perl -Mops=:default ...    # only allow reasonably safe operations
10
11         perl -M-ops=system ...     # disable the 'system' opcode
12

DESCRIPTION

14       Since the "ops" pragma currently has an irreversible global effect, it
15       is only of significant practical use with the "-M" option on the
16       command line.
17
18       See the Opcode module for information about opcodes, optags, opmasks
19       and important information about safety.
