(Apologies for responding to a somewhat old thread, but) Argonaut does not
use runtime reflection - that was one of the goals of the project right
from the start. There's a good presentation about it by two of the original
authors: https://www.youtube.com/watch?v=fBiLrPbZxxM.
I use Argonaut in several Android projects and it works extremely well.
I've found it to be way more principled than any other Scala JSON library
out there.
