5589	Duplicate type signature not reported	MikolajKonarski		"With todays HEAD, as well as one a couple of moths ago (but not with 7.2, I'm told), the attached program does not cause an error or a warning. The crucial fragment is this

{{{
bbb, aaa :: Int
aaa :: Int
}}}

With the ""bbb"" removed, it does lead to error. I guess at least a warning should be issued."	bug	closed	normal		Compiler	7.3	fixed			Linux	x86_64 (amd64)	GHC accepts invalid program		rename/should_fail/T5589
