A further argument for this notation is its close resemblance to the notation with function composition:
insert 1 a . insert 2 b . insert 3 c $ dict
... of course keeping in mind that that's exactly the "wrong" way to compose functions. See any algebra textbook for definition of (f . g) (namely, first apply f, then apply g)
Aaaah.. No... That's not the way I learnt it at least, and it's not how it's defined in Haskell. f . g x = f (g x ) First appy g, then apply f to the result... See e.g. http://mathworld.wolfram.com/Composition.html /S -- Sebastian Sylvan +46(0)736-818655 UIN: 44640862
