Not that I know of. I was also surprised that ` was allowed. But

put 42 into `

is a valid statement. It seems like more of a parlor trick than
something that could be turned into a clever hack. And I also think
it's a bug resulting from the ` character's place in the ASCII table.
I notice that @ and _ and ? are also accepted as variable names.
That's just wrong. You can hurt yourself playing around with these
things.
