I have so many views upon all this, thanks to my new (not released as 
not ready) web service framework. But druntime right now is not ready 
for proper reflection. There needs to be some modifications to it and 
dmd. But mostly druntime for RTInfo.

For example what shouldn't needed to be done. Here is my install 
information for my autoconfig system. (Allows for publically importing 
any module I want AND handling any symbol that the system has used.

#Install

## Configure per type

RTInfo requires a single modification.
[Based upon a forum 
thread](http://forum.dlang.org/post/majnjuhxdefjuqjlpbmv@forum.dlang.org).

```D
template RTInfo(T, string moduleName = __MODULE__)
{
     enum RTInfo = cast(void*)0x12345678;
	
	static if (__traits(compiles, {import core.config;})) {
		import core.config;
		alias checkResult = TypeCheck!(T, moduleName);
	}
}
```

## Auto imports

COPY/core/configimports.d needs to be copied to import/core/configimports.d

Also needed is object.di under imports to be modified.
Add ``D public import core.configimports;`` anywhere you want.
