Ah yeah, I quite like that. I tried to implement the 
`var.should_bort!bool` syntax, but I can't pass an additional 
type parameter to opDispatch, other than the string of the method 
it's dispatching to. Is there a way to do that? Something like 
this:

struct Params
{
private:
	Variant[string] vars;

public:
	T opDispatch(string op, T)() @property
	{
		return vars[op].get!T;
	}
}
