Hello,
When calling a macro, the variables can be dereferenced but they are not
DEFINED, and the list() command fails in several way (please have a look
at the attached test for more details)
Is this a wanted behaviour? If it is, perhaps it should be documented in
macro() command documentation.
Cheers,
Daniele
