Variable Introduction.

**Variable Introduction**
There are a few places where it is desirable to be able inline the declaration of variable.
An example of this is *out*/*byref* method parameters.
```vbnet
Dim IsValid = Integer.TryParse( text, Out value )
```
In this case I am using `out` as the method of variable introduction, which is in keeping with the style / grammar being proposed for C#

There are language proposals where additional usage of variable introduction are possible.
#119
```vbnet
Dim state = TypeOf obj Is T InTo ObjT
Case Is T InTo Obj
```
In this code I am using `InTo` as the method of variable introduction. This style usage is borrowed from LInq
query syntax.
