It does have the disadvantage of variable capture, namely the "x" is
hardcoded in the Scheme function. I tried to return:
parm
(list 'unquote parm)
(list 'eval parm)
instead, but this breaks interactive editing: e.g. typing '^' in math
mode doesn't make a superscript anymore, but a '^' character. The best
I could find is:
(tm-define (my-scheme-macro parm perm)
(:type (tree -> tree))
(:secure #t)
(with path (tree->path parm)
(display* "\nparm(" path ")\n"))
`(arg ,perm))
and call with:
<assign|self-path|<macro|x|<extern|my-scheme-macro|<quote-arg|x>|x>>>
Do you have a better solution?
Thanks for all your help,
