I'd go one step further with Complex, to say that Range isn't a useful

I promised some further thoughts; here they are:
As written, declarator aliasing attaches the alias to a piece of code,
and draws both the name and the alias from that. What about using a
special case of the declarator block for this? That is:

The obvious (default) choice for a step size would be the precision of
the more precise of the two values. So 0.0001 in your example above.
