So it does seem that a function named "a[0]" is valid in default mode.
Of course it is.

So taking that text strictly, "unset a[0]" should attempt to remove the
variable a[0], and if it does not exist, attempt to remove the function
a[0] that name.
As long as there isn't an existing array variable a. In this theoretical
exercise, trying to remove an unset subscript and actually removing a shell
function would be worse.
