* module/system/base/syntax.scm (define-record): Define the accessors as
procedures-with-setters, not just as getters.
* module/system/il/compile.scm (optimize): This function was bitrotten
since the addition of source locations in
cb4cca12e7. Untested attempts to
de-bitrot it. Dedottify as well.
* module/system/il/ghil.scm:
* module/system/il/glil.scm (unparse):
* module/system/vm/debug.scm (debugger-repl): Ongoing dedottification.
