The '()/#f equivalence was dropped a long time ago. Way back in 1997,
according to the NEWS file. I know a lot of people are still using
prehistoric versions like 1.4 or 1.3.4, but I think you may be taking
it a little too far.

Case sensitivity of symbols, BTW, is configurable, although the default
is still case sensitive.
