[Monodevelop-devel] Working on the monodevelop dom after 2.2

I'm fine with that.

I'm not sure what's the best way to approach this.
For a lot of languages, file-level separation doesn't make sense: it
may require the contents of multiple files (whose relationship is not
explicitly specified at the source level) to build a coherent model
for any one file (Vala); nodes may be declared and/or defined across
multiple files (C, C#, Ruby, Python); etc. These issues can be worked
out / worked around while retaining the IFile model, but IMO they
/should/ be worked out before any code gets changed.

It would be nice to have a more "global" (per-solution? per-project?)
builtin parse db that's a sink for any/all parse operations, and _the_
source for completion, quickfinder, folding, class browser,
refactoring, etc.

Works for me - I keep having to manually offset my DomLocation values
in order for folds and things to show up at the right spots.
