Hello,

When I try to render a byteString template using outputFPS like this :

outputBsTemplate :: StringTemplate ByteString -> CGI CGIResult outputBsTemplate template = let bs = renderFPS template in outputFPS bs

I get this error :

Couldn't match expected type `Data.ByteString.Lazy.Internal.ByteString' against inferred type `ByteString'

It's expecting a Lazy bytestring and you're giving it a Strict one. Simplest fix: import Data.ByteString.Lazy instead. Luke
