Summary: Scoping error in lambda expressions in arrow code
Initial Comment:
GHC 6.2.2 with the -farrows switch erroneously reports
errors when lambda expressions appear in
commands. The error looks like the following:
Command-bound variable `y' is not in scope here
Reason: it is used in the left argument of (-<)
This will produce the error:
foo = proc x -> arr (\y -> y-1) -< x
This will not produce the error:
bar = (\y -> y-1)
foo = proc x -> arr bar -< x
