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 package 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.
