Ok. I've changed my strategy: 
if (
  running_under_windows
  and
  Foo.pm loaded
  and
  package_Foo doesn't exist
) { warn about case of Foo }

The reason that 
use Strict;
$x = 10;

[download]
is valid is because use is merely: 
BEGIN {
  require Strict;
  Strict->import;
}

And on Windows, require Strict goes through fine, thanks to the caseless OS. And import silently fails (as is documented).

The DaTA::Dumper thing didn't give an error because you didn't turn on warnings. If warnings were on, you'd have seen: 

Name "main::Dumper" used only once: possible typo at -e line 1.
Filehandle main::Dumper never opened at -e line 1.
