Unattended source-to-source transformation is fairly
easy in s-exp-based languages. It may well be one of
the selling points of such languages. For this reason,
I doubt that Lisp2 is being reluctantly tolerated
merely for backward compatibilty. I should think
people actually want it, and for new programs. The two
reasons I have heard consistently offered by Lisp2
(a) they want to use "natural" variable names like
`list' (although the unavailability of `t' seems OK)
without worrying that it will clash with function
(b) defmacro-based macros (allegedly) risk no or
fewer variable-capture problems.
