[Haskell-cafe] ????Pattern match(es) are overlapped???

I am implementing HTTP and I have something like:
newtype Method = Method String
getMethod = Method "GET"
putMethod = Method "PUT"
doMeth getMethod = ...
doMeth putMethod = ...
GHC gives me a patter matches are overlapped
And when I run, I discover that pattern matching
is not actually happening. getMethod is
always executed even though the method passed
What am I doing wrong?
