subs(3) subs(3)
subs - Perl pragma to predeclare sub names
use subs qw(frob);
frob 3..10;
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 the section on Pragmatic Modules in the perlmod manpage and the
section on strict subs in the strict manpage.
