In the short term I'd go for the trade-off rather than the ideal: it'd be great if the compiler could transparently support what the interpreter already supports, like Elisp, `reader-options' and `current-reader' to some extents (am I biased? ;-)). Something like MzScheme's "#lang" may be nice but I see it as the next step. Thanks, Ludo'.
