Subject: to me, the problem:
X-Git-Tag: make_still_working~3485
X-Git-Url: http://matita.cs.unibo.it/gitweb/?a=commitdiff_plain;ds=sidebyside;h=686f7f4f4444125885bc7ef9e8ec3e0b6f567137;hp=686f7f4f4444125885bc7ef9e8ec3e0b6f567137;p=helm.git

to me, the problem:
  ? t ==?== ?->?
where the first ? has an empty local context
is always Uncertain... to be fully understood
why unification gives Failure. It may be correct if
t has type (Rel k). I wrap it in the refiner.
