'use module' statements have file scope.

They have package scope. Or rather, the require portion has program scope, the import portion has package scope.

package Foo;
use Benchmark qw{cmpthese};

package main;
cmpthese( -1, { ...etc... } );

__END__
Undefined subroutine &main::cmpthese called at - line 7.

update: It's worthwhile to add that import acting in package scope is conventional, not a rigid truth. import is free to do what it wants, but it is usually defined by Exporter (or like Exporter) to inject symbols into the caller's package scope.
