[Hat] hat error with HUnit: Variable not in scope: `TPrelude.fnegate'

[Shae Matijs Erisson]

I'm using HUnit (http://hunit.sf.net/)

I think the snegate, gnegate, and pnegate are type specialized tracing functions.
Hat can't find fnegate, and the source before rewriting points to a handle, stdout I think.
Or maybe I'm just missing something?

Here's the error:
