 subs - Perl pragma to predeclare sub names


NAME

subs - Perl pragma to predeclare sub names


SUPPORTED PLATFORMS

  • Linux
  • Solaris
  • Windows

SYNOPSIS

    use subs qw(frob);
    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 the perlmodlib manpage and strict subs in the strict manpage.
