code that skips over them when building the search indices.
Overall, this means that the only change most people would see
is that multiple constructors in the same class will get a warning
(and there was one of those, so fixed that too).
Also, Rackety. Specifically, transformed this surprising combination
of constructs (where all caps are placeholders for something specific):
((if PRED
(λ (c mk) BODY2)
(λ (c mk) BODY1))
content
(lambda (tag) BODY3))
into this one:
(define (mk tag) BODY3)
(if PRED
BODY1{c:=content}
BODY2{c:=content})
