ok.

This must make the following syntax rule illegal:

 target = null

because if "null" is declared as a .local, you can't know whether you want
to nullify target, or want to set target's value to that of the .local
variable "null".

I take it this is no problem; just stick to

 null target

if you actually want to set target to 0/null.
