Comment (by vlaad):
Well, if this is *not* a bug, then please explain how in your first
response we are getting an empty list? (or better, stop thinking, and pass
it to the guys, please).
("Perhaps you mean [x|x<-[1..200],x`mod`6==1,x`mod`6==5]")
{{{
Prelude> [x|x<-[1..20],x`mod`6==5]
[5,11,17]
Prelude> [x|x<-[1..20],x`mod`6==1]
[1,7,13,19]
Prelude> [x|x<-[1..20],x`mod`6==1,x`mod`6==5]
[]
}}}
