Nor will it ever be --- that's quite a serious bug. `let' needs to
get each expression as one single argument, so it should be
builtin let "fun == 0"
and I'm pretty sure it was until not all that long ago.
In fact, Zoltan has improved the lexing of ((...)) so that it's no
longer quite the same as a double quoted expression, so that my
original hack of turning the former into the latter for ease of
reconstructing the text is not quite so appropriate.

This won't help here, but maybe == is common enough as a test to have
a special case anyway.
