Hi,

How do you deal with indentation when using syntax extensions? Tuareg,
otherwise genial, instead of helping, "messes" the source using them. By
extensions I mean Meta OCaml, Fresh OCaml, user extensions using Camlp4.
More, Tuareg fails to indent record types with polymorphic fields.

One solution would be to use generic indentation and other goods a la
Semantic's. It takes a BNF-style grammar.

An ultimate solution would be to port Camlp4 to Semantic to parse the OCaml
source and pass the (translated) parse-tree to Semantic. This would require
incremental parsing by Camlp4. At present, Semantic 2.0 uses Bison.

More straightforward solution is to make the syntax indented by Tuareg
customizable.

Cheers,
Lukasz
