So, how about this...

Dim x As Integer = 0

Will the following produce true?

If x = Nothing then
....
End If

Zero is the default value of an Integer type, yet I have explicitly set its
value to zero, so how could I get a true when testing against Nothing?

Try it...
When x = 0, "x = Nothing" evaluates to 'True'

Well, I'll be!

I'm not sure I am comfortable with that behavior though.

I could write a book on VB weirdness...
The problem is the way VB has developed over the years. It's almost as if
the VB design team has simply responded ad-hoc to user requests, no matter
how half-baked ("why can't I add parentheses to property calls?" "why can't I
omit parentheses on method calls?", "why can't Nothing apply to value
types?", "why do I have to declare my variables?", etc.).

Well, the last one would rather be the other way around, as not
declaring the variables was how it was done in BASIC.

"Why can't I declare my variables, as you do in a real programming
language?" ;)
