The point here is that macro arguments are still different from
environment variables (see the documentation on TeXmacs primitives;
one day this distinction may disappear, but not within the next few months).

Nevertheless, it is always easy to locally assign an environment
variable with a macro argument using the "with" primitive.
Alternatively, you can use some macro-magic so as to substitute
the argument by its value in the body: see the (detailed) documentation
on quoting and quasi-quoting and the examples given there.
