Maybe you need a semicolon here?

(system base lalr).

I don’t think so.  Only the Scheme and Emacs Lisp front-end are
reasonably mature, anyway.

FWIW, I don’t quite buy the “dynamic language compiler collection”.
Others tried this before (Parrot), with some success in terms of
supported languages, but not much beyond that.

In terms of strategy, I think Guile’s focus should remain primarily on
Scheme variants, and ELisp.  Other language front-ends are of course
welcome, but we must keep an eye on what the demand is.
