I discovered a problem with the pretty-printing of some terms (I am
using revision 4392eb046a97).
term "(λ(a, b) (c, d). e) x y"
"case_guard True x
(case_cons (case_abs (λa. case_abs (λb. case_elem (a, b) (λ(c, d). e))))
case_nil)
y"
:: "'e"
I assume this is a result of the recent changes to the handling of
case expressions?
