I don't understand what you mean: it's not a workaround, as you have to define
your block once. Then, you simply use its name, instead of naming a call line,
and using that name. You avoid one indirection, no?

I don't know if that's the solution, or simply a feature which works for now.

I find this weird and unsound:

- For code blocks, the results' name (curdir) is the code block's name

- For call lines, as you do above, you give another name to the results of a
  call line (myname) than the name of the call line itself (curdircall).

This is not appealing to me, and confusing at least.
