The transformations that the compiler does, especially with -O,
are sufficiently complex that trying to second-guess the performance
effects of source changes is difficult. You'd get a much better
handle on this by reading the post-optimised program, which you
can get with -ddump-simpl. Good
The warning says that the interpreter has ignored a

should still behave the same, although possibly less strictly

What really mystifies us is why there is such a thing in the

| Anybody knows how to generate a portable C code through GHC ?
It depends what you mean by portable.
GHC can produce C code which you can compile with gcc, without
