To cut a long story short: the problem hasn't progressed.

However, your analysis is entirely correct: defining a macro for the
TRULY-THE form would indeed by the short term solution. My thoughts would
be to remove the special form longer term. Even though we have
special-purpose compilation support for it, I don't see benefits in keeping
it around. It's supposed to allow increased performance for compiled
programs. So, upon removal, we probably need to verify that the performance
degradation is small enough.


Bye,


Erik.
