<h1><a name="description">DESCRIPTION</a></h1>
<p>This will predeclare all the subroutine whose names are 
in the list, allowing you to use them without parentheses
even before they're declared.</p>
<p>Unlike pragmas that affect the <a href="../lib/Pod/perlvar.html#item___h"><code>$^H</code></a> hints variable, the <code>use vars</code> and
<code>use subs</code> declarations are not BLOCK-scoped.  They are thus effective
for the entire file in which they appear.  You may not rescind such
declarations with <code>no vars</code> or <code>no subs</code>.</p>
<p>See <a href="../lib/Pod/perlmodlib.html#pragmatic_modules">Pragmatic Modules in the perlmodlib manpage</a> and <a href="../lib/strict.html#strict_subs">strict subs in the strict manpage</a>.</p>
