+=head1 NAME
+
+subs - Perl pragma to predeclare sub names
+
+=head1 SYNOPSIS
+
+ use subs qw(frob);
+ frob 3..10;
+
+=head1 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 C<$^H> hints variable, the C<use vars> and
+C<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 C<no vars> or C<no subs>.
+
+See L<perlmodlib/Pragmatic Modules> and L<strict/strict subs>.
