Hmm... to!int(str) seems to be working for me. The issue is probably that when 
doing such a conversion, the _whole_ string must be convertable. So, no extra 
whitespace or whatnot. If you're looking to take multiple values out of a 
particular string or you might have whitespace in it, parse() is a better 
choice. But to() should work just fine as long as the string is exactly 
convertable to the type. As I understand it, to() should be able to convert 
pretty much anything to anything as long as the type has the appropriate 
conversion functions defined.
