There are definite similarities, yes - I only became aware of 
testing-feat very recently.   You seem to have concentrated more on 
efficiency, while we have focused more on the high-level modular design 
and on strategies.  We should probably merge our efforts, if you are 

I mistakenly build the release to upload to hackage from an experimental 
branch (which is currently broken).  The sources on github work.  I'll 
update gencheck shortly to fix this, sorry.
