Actually the cpp-style pragma is only recognised if the '#' is in the leftmost column and is followed by optional spaces and a digit. It's quite hard to write one of these in a legal Haskell program, but not impossible.

It's enough to change Manuel's program to use {;} instead of layout. But it won't happen in any real life program.

A dangerous statement. For example, automatically generated code often contains quite strange code. If something breaks the standard, it breaks the standard. Cheers, Manuel
