Subject: Fix Trac #2714 (a minor wibble)
X-Git-Url: http://git.megacz.com/?a=commitdiff_plain;h=e1202fd33a406f4fc4f78d60a0dd48c030b7c9cf;hp=e1202fd33a406f4fc4f78d60a0dd48c030b7c9cf;p=ghc-hetmet.git

Fix Trac #2714 (a minor wibble)

In boxy_match (which is a pure function used by preSubType) we can
encounter TyVars not just TcTyVars; this patch takes account of that.
