No. And besides, you would want to unset *first*, right?
What are you actually trying to do here?

Because it's a valid assignment to a perfectly acceptable variable.
It's the same as:

cd /tmp
There's no conflict. The first one is an assignment to a variable named
cd. The second one is a cd command.
