subs - Perl pragma to predeclare subroutine names
use subs qw(frob);
frob 3..10;
This will predeclare all the subroutines whose names are in the list, allowing you to use them without parentheses (as list operators) even before they're declared.
Unlike pragmas that affect the $^H hints variable, the use vars and
use subs declarations are not lexically scoped to the block they appear
in: they affect
the entire package in which they appear. It is not possible to rescind these
declarations with no vars or no subs.
See perlmodlib/Pragmatic Modules and strict subs in the strict manpage.
