I would not lightly prohibit the use of spacing conventions that have proved over centuries to aid in understanding syntactic strucure. For example, this code fragment to define addition on lists is instantly intelligible. instance Num a => Num [a] where (f:fs) + (g:gs) = f+g : fs+gs But the formula becomes merely an obscure procession of symbols when rewritten with the operators set off by spaces: ( fs : gs ) + ( g : gs ) = f + g : fs + gs And it becomes too long and too subtly modulated to take in at a glance if more spacing is added to emphasize precedence: ( f : fs ) + ( g : gs ) = f + g : fs + gs Doug McIlroy _______________________________________________ Haskell-prime mailing list Haskell-prime@haskell.org http://www.haskell.org/mailman/listinfo/haskell-prime
