* Supporting class-level declarations
- It currently has a few problems:
+ Currently the evaluator has this feature disabled, to enable
+ it edit the eval.cs file and make this be the default:
+
+- parser.Lexer.putback_char = Tokenizer.EvalUsingDeclarationsParserCharacter;
+- //parser.Lexer.putback_char = Tokenizer.EvalCompilationUnitParserCharacter;
++ //parser.Lexer.putback_char = Tokenizer.EvalUsingDeclarationsParserCharacter;
++ parser.Lexer.putback_char = Tokenizer.EvalCompilationUnitParserCharacter;
- * Support for overwritting existing defined
- classes is not supported.
+
+ It currently has a few problems:
* The usability is not as useful, since the defaults
for C# are still to make members private, we should
change this default to be public in those cases.
- * The error lookup system lacks information from types, for
- example this causes an unsupported call into a TypeBuilder:
-
- csharp>class D { void DD () {} }
- csharp>var d = new D ();
- csharp>d.DD ();

- The above is caused by TypeManager.LookupDeclSpace (dt)
- failing to return a value (it returns null) so our code
- assumes we have an Assembly instead of an assemblybuilder.

-* Declaring a class twice produces an internal parse error:
-
- class X {}
- class X {}
-
- The second declaration will no longer be parsed, so it could even
- contain junk, and wont be flagged. We probably need to allow for
- type redefinition in REPL modes, the exception from the second is:
-
- csharp -v -v
- > class X {}
- > class X {}

-* Important: we need to replace TypeBuidlers with Types after things
- have been emitted, or stuff like this happens:
-
-csharp> public class y {}
-csharp> typeof (y);
-Class1

* Clearing data
TODO: when clearing data for variables that have been overwritten
This is easy to implement, just retry the parse with a
semicolon, the question is whether this is a good idea to do
in the first place or not.

+Completion support
+==================
+
+ Supported:
+
+ a.<TAB> to complete members of type `a'
+ a<TAB> for types and namespaces
+ a.W<TAB>
+ a<TAB> for local variables

+ Unsupported:
