so, i think, it is needed to "reassure" imperative programmers at first pages by demonstrating techiques of imperative programming, including conditional execution and IORef/MArray and only after that present more convenient alternatives. at least for my imperative feel, conditional execution, cycles, modifiable variables and arrays together form enough basis to implement any algorithm

Can't DC> tell if you're serious. yes, i know that this viewpoint is extreme. but i said not about my current thoughts, but about my history of "buying" Haskell. i first found it in 2003, mastered all the "gentle introduction" except for monads and rejected. the second try in 2004 was more successfull. so i will repeat my point - i as imperative programmer need to "feel basis" and to know that in worst case i can write imperatively parts of program which don't fit in pure style. this not requires full explanation, just mentioning and may be examples (although these examples will sjow weakness of imperative Haskell facilities) -- Best regards, Bulat mailto:bulatz@HotPOP.com
