It's due to the distinction between finding a symbol and knowing its type.
Goto-definition does work here because Wing knows where the symbol is
defined.

In this case I think Wing is failing to extract the type from the way
assertTrue is defined:

   assert_ = assertTrue = failUnless

This case is on our list of things to add to the type inferencer.
