Thanks for the great survey Amirouche! I haven't tried Spock either. If
Peter is reading, maybe he knows about its current status?

Would it be worth specifying a version of Scheme without tail calls and
continuations (I know..) that maps easily to JavaScript? Various Scheme
compilers could emit this restricted form of Scheme, which would then be
simple to translate to JS. Hash-table support could also be modified so
that Scheme hash-tables map easily to JavaScript objects.
