[Haskell-cafe] Re: Why functional programming matters

[Isaac Dupree]

fewer frustratingly unsolvable bugs down-the-road?  When I have bugs in 
my Haskell programs (and usually I get type errors instead), I've always 
found them eventually and they're either a silly mistake or I realize 
that I misunderstood the problem I was trying to solve (it needs to be 
solved a different way)... which is great, being able to realize that 
and rewrite things!  Usually not everything has to be rewritten because 
Haskell is pretty modular (unless used poorly :-).
