At the moment you can set the gspec to nil, but that would simply disable s/fdef generation and all of the spec-related magic. I'm planning to introduce a configuration option with the next release to force Ghostwheel to trust that there's an external s/fdef for that function and still do all the spec stuff.

There may be some limitations on this compared to using inline gspecs – I have to play around with it a bit, but I think it should work fine. Until then, you can still use Ghostwheel for tracing and side effect detection though.
