It's not as bad as I initially thought; the current-*-port is handled as
a special case, so it's actually safe to update them with fluid-let.
This could be simplified by using parameters, though.

The compiler uses it in a few places to temporarily override the value
of a global variable.  This is fine, but if we ever decide to turn the
compiler into a library, it wouldn't be thread-safe.  So this might
better be rewritten.
