unknown type is fine, this is a trivial little bug that should be able
to be fixed with 2 lines of change.  It might be marginally better
with EMN[], but, the cost is once EMN is inside of `things' (such as
[]), the code that has to check stuff as you rip apart stuff
increases.  And without the checks in place before you begin, you
increase the faulting before you improve the diagnostics, which, isn't
an improvement.
