For macros that generate macros, I think you need a way to escape the
splicing and maybe define how splicing works in an inner quasi quote.
I guess you want <[ <[ $exp ]> ]> to turn into the ast <[ 1 ]>
Then if you wanted ast <[ <[ $exp ]> ]> with the splice associated with
the inner quasi quote, you'd have to do something like
<[ <[ <[ \\\$exp ]> ]> ]>
maybe a way to associate a splice with a quasi quote?
<a[ <b[ <c[ $(a, exp) + $(b, exp) + $(c, exp) ]> ]> ]>
a's exp is A
b's exp is B
c's exp is C
then splice the quasi quote N times:
1: ast <b[ <c[ A + $(b, exp) + $(c, exp) ]> ]>
2: ast <c[ A + B + $(c, exp) ]>
3: ast A + B + C
just dinking around here
This would require some thought.
