In all programming languages the first operand gives the type of the
expression. That's why it works to concatenate integers to string in the
fashion:
"abc" + 123
Try 0 + $null and see if it is integer.

I added 0 to $null in order to get int. If I had added
"0" the result should be string. So this looks like a bug to me. If I add 0,
result can't be string.
