Comment (by afarmer):

 Please do merge the commit referenced in comment:15!

 HERMIT (for better or worse) still relies on rules pragmas to specify
 equational properties. The "fix huge space leak" commit mentioned in
 comment:12 effectively prevents us from using HERMIT with 7.10.2 because
 the left-hand sides of rules are being rewritten before they get to
 HERMIT. (Apologies for not spotting this earlier... I've been traveling
 this summer.)
