Referencing the previous tracker issue,
another use of this syntax also applies to the following
judiciously modified/simplified snippet:

         %push

         %assign %$arg 8

         %macro local 0
             %xdefine %[%:] ebp-%[%$arg]
             %assign %$arg %$arg+8
         %endmacro

         _main:

         .myvar local  ; results in _main.myvar defined as ebp-8
         mov rax, [.myvar]

         %pop

I personally prefer the %: syntax as it is slightly less confusing than %00.
However, bear in mind that previous snippet is modifying the local label
for it's own use and that this behavior should continue being supported
following any syntax change.
