To further this, I would love to see something where "quick POD structs"  
can be constructed using some builtin syntax.

For example:

{valid:bool, value:int}

which would be equivalent to Tuple!(bool, "valid", int, "value")

I would *definitely* like to see that.  This might be on par with the =>  
addition.
