  * Fix #3067: GHCi panics with 'initTc:LIE' while :stepping on code with
 funny types

  The problem is that calls to boxyUnify would panic if the types involved
  contained type functions.
  It looks like one should wrap these calls with getLIE, although I don't
  really know what I am doing here
