Compatibility with `std::intrinsics::type_name`

[gandro]

It looks CI is currently failing on nightly due to changes in how std::intrinsics::type_name report the names of aliased types. For example, Box is now reported as alloc::boxed::Box instead of std::boxed::Box.

If this new behaviour is not a regression in Rust, we should eventually release a v0.2 with the new behaviour as this would be a breaking change.
