I'm not a native English speaker, so what does "*just* as good" mean
in _this_ case? :) "ok, use it if you want", or "as good as", or
"better than"?

I say TypeOf is to be preferred because it's "just quicker".
About 3.5x quicker (in my personal, I predict that one will say
disputable, tests). (yes, and I do know that both methods are not the same
because TypeOf includes inherited classes). And, BTW, TypeOf is 1:1
translated to the "isinst" IL keyword.

Curly braces in C are also traditional. AND THAT DAMNED
CASE SENSITIVITY TOOOOO! Ummm... sorry, Sunday morning... ;)

Then, I should have said "you way is better". I stand corrected.
Thanks, Armin. I was not aware of the significant performance difference.

Pay close attention to Armin's latest post. Note the significant improvement
difference using TypeOf.
