Hi. I'm really new to Haskell, just learning it, and I must say I'm pretty overwhelmed by the large variety of constructs. (=>, <-, \ to name a few)
Would that be \ as in TREX row variable polymorphism? Just remember most operators are just library functions. It's only =, ->, =>, <-, :: that are really part of the language, and {,},; for grouping. Did I miss any?
Yes, you missed \, which is used for function abstraction: (\x -> x*x) 3 And ( , ) for tuples. And I don't think "->" is part of the language - it only appears in the type syntax, not term syntax. If you allow it, you have to allow * as well. --KW 8-) -- Keith Wansbrough <kw217@cl.cam.ac.uk> http://www.cl.cam.ac.uk/users/kw217/ University of Cambridge Computer Laboratory.
