@unnumbered Perl pragma to restrict unsafe operations when compiling


@unnumberedsec NAME

ops - Perl pragma to restrict unsafe operations when compiling

@unnumberedsec SYNOPSIS  

@example
perl -Mops=:default ...    # only allow reasonably safe operations
@end example

@example
perl -M-ops=system ...     # disable the @'system@' opcode
@end example

@unnumberedsec DESCRIPTION

Since the ops pragma currently has an irreversable global effect, it is
only of significant practical use with the -M option on the command line.

See the @xref{Opcode,Opcode}, module for information about opcodes, optags, opmasks
and important information about safety.
