I want to use Test::Warn in my tests. Since it has many dependencies, I might not have that module on every system that I want to run the tests. So I need to skip the tests that uses this module.

Normally, I would do: 

use Test::More qw(no_plan);

SKIP: {
    eval { require Test::Warn };
    skip 'Test::Warn not found', 1 if $@;
    warning_like { warn "warning!" } qr(warning), 'basic warning';
}

But, on a system that does have Test::Warn, this will fail with this diagnostic message: 
Can't call method "warning_like" without a package or object reference
If I use Test::Warn instead, the above test works (and of course, fails on systems that don't have Test::Warn).

I read documentation on use and require, but I cannot figure out how to get around this problem. (Since perl is not complaining about the exported symbol "warning_like", I assume that import has been successfully run by the time that line is executed.)

I'd appreciate any help.
