Lightweight syntax option in F# 1.1.12.3

Coming from Ocaml but having also programmed in Python, Boo and Haskell i have to say that i don't like that feature much for a caml like language. It makes sense for python and for haskell too but for staying close to ocaml it should stay optional and not be the default setting. Just saving a few in's here and there is not a good argument for introducing such a "feature". It also hides the fact that things declared with "let ... in" are defined for the actual scope (just using identing for this is not as clear). So i think it does not make the source code clearer but is more confusing even more for beginners. Ocaml folks have their own indentation rules mostly coming from the tuareg mode of emacs and if they switch to F# they will be a bit disapointed. A great strength of ocaml is the ability to indent the code as the programmer wishes.

I tried the Visual Studio 2008 F# prerelease and was dismayed of all the "errors" i did get when writing code until i discovered this "feature". So please let it at most be optional and please not the default setting for writing F# code. A lot of people switching from ocaml or other languages will thank you a lot.

Mattias, OCaml automatically indents code for you.

thanks for the implementation notes at the end. ive been a boo fan for a while, an indent-aware python-inspired dotnet language. although the parser has always supported indentation, theres a number of added features we're trying to coax our tokenizer into doing. we still havent added the parsers routines to dump inline ndoc, and the interpretter still cannot process the backspace key (since characters are fed in via an S.I.Stream). just two silly things, but both seem much more complex when you try actually effecting change. i greatly enjoy hearing tales of other people modifying their compilers and systems to the benefit of coders and wrists everywhere, and its wonderful hearing the technical successes behind this growing and altogether-wonderful project.

Wonderful! It is rather easy to create buggy programs in Caml using nested match, and you will not get any warnings.

Maybe an option is to still use "(, ), begin, end, in", and get a warning if the indentation isn't consistent with the "(, ), ..."
