The point isn't really the (include "..."). That's just what I happened to use the 'if' capability for. The true and false expressions could theoretically be any valid top level CGEN construct. Implementing conditional capability for them all seems like a lot more work for no gain and may not even make sense in some cases. Also 'cond' or 'case' could easily be added as top level tests if necessary.why not allow computed `include' instead? (perhaps that is already supported?) something like:
(include EXPR)
then EXPR can be all manner of `if', `cond' or whatever. e.g.:
(include (if (application-is? SID-SIMULATOR) "sid-macros.cpu" "sim-macros.cpu"))
(include (cond ((application-is? SID-SIMULATOR) "sid-macros.cpu") (else "sim-macros.cpu")))
(include (case (application->symbol APPLICATION-OBJECT) ((SIMULATOR) "sid-macros.cpu") (else "sid-macros.cpu")))
