Comment (by simonpj):

 My compiler, compiled with -DDEBUG, gets an assert error.

 What do you expect?  You're doing
 {{{
 (unsafeCoerce IsEqual) undefined undefined
 }}}
 that is, applying a non-function as a function.  Would you prefer a seg
 fault?  Unsafe coerce is, as it says, unsafe.

 What would be the right behaviour?  A type error?  Presumably not, since
 you have consciously suppressed that.

 Simon
