Yeah, that's what I meant. Hmm. And aren't there probably some other way
to invoke the bytecode interpreter from the GHC API? It might be nice if
all such ways would give the same exception...

support the different closure representations and other conventions of the
profiling build.
Hmm. I was expecting something more along the lines of "so make another
