scala parse a string into a Tree to use in a quasi quote

I was wondering if i could perform a sort of a nested quasi quote evaluation.

Let's say i have a function call

q"${function(args)}"

That returns "add(x,y)" (a string)

How can i make it evaluate this?

Something like

val a = q"""${q"${function(args)}"}"""

The problem here is that the first evaluation of the quasi quote is return a String which than leads to nothing being performed in the second evaluation.

What result `Tree` are you looking for? – Michael Zajac Jan 05 '17 at 16:26
basically i wanted to parse a string into a `Tree`. Is this possible? – raul ferreira Jan 05 '17 at 16:30
Okay, but what _exact_ `Tree` do you want to get from it? – Michael Zajac Jan 05 '17 at 16:41
a tree that can be evaluated in a quasi quote in the form `q"$tree"` so tree would be something like `val tree = add(x,y)` – raul ferreira Jan 05 '17 at 16:43
