I don't think you even need to make it local, since $0 is handled
similarly to the other positional arguments.

% fn() { 0=foo; echo $0; }  
% fn
foo
% echo $0
zsh

This fact should probably be construed as a genuine feature.  If you're
asking, is some bright spark going to decide that $0 should be different
from $1 to $infinity and break it, I can't answer that, but it won't be me.

Actually, Peter, you're already too late.  That had better be

	fn() {
	  setopt functionargzero
	  0=foo
	  echo $0
	}

Otherwise, assigning to 0 in the function assigns to the "global" $0.
