You are right! Thank you. That's a bug in my proxy too. I'll figure out how to fix it in 0.1.2 soon. This is early alpha, and the things you're noting are valuable bug reports. But none of this is fundamentally unfixable in a library, nor even especially difficult. I doubt I'll ever even use my own software. It's just a proof-of-concept that we can achieve the ACTUAL purpose of PEP 505 with no language changes. I don't very often have a need to solve the problem PEP 505 does... even though I very often work in the very domain it is intended to address (semi-structured nested data). Even if the PEP could be a little bit more elegant for a very few circumstances, it's just not anywhere close to deserving syntax... especially not syntax that even proponents tend to misunderstand the semantics of. -- Keeping medicines from the bloodstreams of the sick; food from the bellies of the hungry; books from the hands of the uneducated; technology from the underdeveloped; and putting advocates of freedom in prisons. Intellectual property is to the 21st century what the slave trade was to the 16th.
