I do not know if that "feature" was an intentional design or an
accident, and I do not know either if it is considered a good practice
or an abuse to take advantage of it, but I find it very useful. It
does not only work with number registers, but also with strings and,
in fact, everything.
I'm using it to write macros on the fly (".de macro:\nx"), and avoid
the if/else tests (".macro\ni", ".macro\nj").

I have the feeling I found it by accident too. Or maybe did I saw it
in the macro ms...
