[erlang-questions] Compiler warnings on impossible constructs?

Hi list,

I today fixed a stupid bug in something I wrote last week, namely, an 
atom-to-atom comparison which should have been a variable-to-atom 

It read: foo =:= bar while it should have read Foo =:= bar.

So, my question is, can't Erlang detect this kind of situations on 
compile time? Obviously, the expression foo =:= bar will never be true, 

Or maybe I just trust flymake to much instead of doublechecking the 
stuff I write.. ;)
