OK, that looks like you can construct an "AST" this way. Nice.

This, however, I do not like. I would expect to be able to either call
just something like var.asString() or to have a visitor traversing the
AST and producing an output text.

Don't you get some pretty-printing / auto-formating for your DSL for
free? You might be able to use the pretty printer to produce the desired
output.

Hope this helps / points you in the right direction.
