Over on this build of the conda-forge feedstock for fastdiff, I've come upon:

I haven't had a chance to check it out locally, but will get to it when i have a chance... will at least turn the verbosity up...

Previous build of 0.1.4...

ah, because compare_native was explicitly set this way in the wasmer-less case (we don't have that just yet on conda-forge):
