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,
