Whoops, thanks Per. After several more mistakes torturing the
compiler, I think I've got the scoping for DECLARE working now. The
code needs cleaning up, and there still a couple bugs (logic errors,
nothing that seems difficult to fix).
Sidenote: I'm having trouble logging into Savannah, but I noticed this
buglet today:
#|kawa:1|# (zero? (define-simple-class))
java.lang.NullPointerException
at kawa.standard.define_class.rewriteForm(define_class.java:122)
...
I've made a note to look into it at some point in the future, but
NullPointerExceptions aren't good, so maybe if anyone else has time,
they could look at why that's happening.
I am truly, truly sorry for these hideous use cases.
Cordially,
Charlie.
