Hi all,
I assume the following behavior has a trivial explanation.

When I write:
case name of
	"a" -> ...
	"b" -> ...
everything works fine.

But when I extract a and b to constants:

c_a = "a" :: String
c_b = "b" :: String

case name of
	c_a -> ...
	c_b -> ...
I get Patterns match(es) are overlapped.

Adam
