Now if only you could declare a new variable within a with statement. It's  
not strictly necessary, but I find

	with (auto tb = new TextBox()) { ... }

to be more aesthetically pleasing than

	auto tb = new TextBox();
	with (tb) { ... }

of course, given that with introduces a separate scope, tb might go out of  
scope the moment the with statement exits. This might be open to  
interpretation though, seeing as tb is declared outside the curly braces.
