As long as the warning is only shown when expansion debugging is
enabled, that sounds like a reasonable solution.

Casting an empty string to zero when forced into a numeric context is
a very reasonable, and precedented, construct used in many other
scripting languages. But if someone enables expansion debugging, it
seems reasonable to show some sort of warning about it.
