That seems pretty theoretical. It's easy to add a "if has variables"
check first. I looked at quite a few libraries grepping for unusual
del statements and didn't find any, including nothing like 'del []'
BTW, there's a bug in the error message for 'del ()'

This is the exception I want to see when someone does a destructuring
del, though with corrected wording.
