Again, the representation as objects isn't a key requirement=2E Python's W=
SGI spec simply has a dictionary (read: associative array) of the environme=
nt based on CGI=2E The application might well turn that into a more powerfu=
l object, but standardisation of such wasn't considered a pre-requisite, an=
d would actually have hampered ASGI, where not all events represent an HTTP=
 request=2E

The key requirement is that you have some way of passing the current reque=
st and response around as scoped variables, not global state=2E That's esse=
ntial for any kind of concurrent run-time (async, thread-aware, etc)=2E

An event / subscriber model fits well with that: the local scope for each =
request is set up by an invocation of the callback with defined parameters =
and return value=2E

Funnily enough, the example of a worker script for FrankenPHP does both th=
ings: it sends each request to the same application "handle" callback, pass=
ing in the super-global arrays as parameters to be used as non-global state=
=2E https://frankenphp=2Edev/docs/worker/#custom-apps So really all I'm arg=
uing is that a few more lines of that PHP example be moved into the C imple=
mentation, so that the user only needs to provide that inner callable, not =
the outer while loop=2E
