In ghc, use the compile-time option -fwarn-incomplete-patterns

Is there a warning to warn if a block is delimited (or not) with a mix of tabs and spaces? Or somehow otherwise warn against dangerously looking layout?

Talking about warnings, it is probably patently stupid to put {-# OPTIONS -fglasgow-exts -package lang #-} at the top of my Main.lhs. But why does GHC (5.04-1) fail to find any of my imports as a consequence? Bug? -kzm -- If I haven't seen further, it is by standing in the footprints of giants
