It is possible to have similar interfaces with different
implementations, using `cond-expand'. lily.scm does this in one case,
implementing 2.0 interfaces on 1.8.
I'll take a look at implementing something like this.
To summarize your issue: you have code like:
(lambda (a b c)
#{ here I have custom code that references lexical variables;
should it be able to set them too? }#)
It would be relatively easy to pass in an alist of the lexicals, for
reference purposes; but do you want to be able to set them too, from
within that EDSL?
Andy
