What about this:
var
_foo: tfoo = nil;
That way you declare it right there and then.. ensuring it is not assigned.
Hence why I think a good human practice is to always init everything
even if it psychologically affects some people in ways such as "will
this slow the program down though? Do I need to init this stuff if I am
going to init some of it later"? which is evil premature optimization
that causes bugs.
