FWIW, last week I played around with this in Rust[0]. The code is pretty
ugly, but I was able to reproduce your script and enhance it with some
PoC queue support. There's a launchpadlib crate that uses the same
approach as the Python lib, so in theory that's actually easier than
Python due to working code completion.
In practice the WADL is actually pretty inaccurate on some things like
whether something is optional or not, or on the proper type of some
arguments. That's not a problem in Python, but it requires serious
massaging in Rust[1]
(FWIW, I'd probably get out the pitchfork if you proposed a new C++
project)
