Sub::Uplevel installs a CORE::GLOBAL::caller subroutine with a prototype that matches CORE::caller. Contextual::Return's CORE::GLOBAL::caller replacement has no prototype -- which is what causes the error if Contextual::Return loads after Sub::Uplevel.

I suspect you could load just Contextual::Return instead of your entire module before Test::Exception and it would work -- I guess replacing an unprototyped function with a prototyped one is not considered an error.

In my view, it's a bug in Contextual::Return, since you want to have the same caller() semantics as without a CORE::GLOBAL::caller override.

my $caller = caller @foo;  # like "scalar @foo"

Yes, prototypes are evil, but core functions do have them, so CORE::GLOBAL replacements should have them as well for consistency.
