subs

Perl 5 version 10.1 documentation

subs

NAME

subs - Perl pragma to predeclare sub names

SYNOPSIS

  1. use subs qw(frob);
  2. frob 3..10;

DESCRIPTION

This will predeclare all the subroutine whose names are in the list, allowing you to use them without parentheses even before they're declared.

Unlike pragmas that affect the $^H hints variable, the use vars and use subs declarations are not BLOCK-scoped. They are thus effective for the entire file in which they appear. You may not rescind such declarations with no vars or no subs .

See "Pragmatic Modules" in perlmodlib and "strict subs" in strict.
