[nem-en] Completion

[vc]

Hi,

1. I try use completion for the following strings:
try_completion ("Fo");
try_completion ("");
try_completion ("def _ = 0; ");

and resalt is errors and exceptions:
================================================
 Completion member: method Example.SomeClass.Bar() : void

2. For implementing complete word in VS 2005 I need to have the list of
accessible substitutions for an empty string (all possible in some context).

3. I do not understand how will work completion if user type code in the
middle of function. For example, if in method body is no closing bracket.

4. I need to receive the list of all accessible types in the project
(declared and imported).

5. If the body of a method changed, all locations below it become incorrect.
But the structure of a compilation units thus does not vary. Well to have an
opportunity to update all locations if method body changed.
