Hi,

I have made basic py2many.pyd work at language/syntax level in my 
dlang fork:

https://github.com/mw66/py2many/tree/dlang

The following examples works now:

https://github.com/mw66/py2many/tree/dlang/tests/expected

py2many/ 13:56:23$ ls ./tests/expected/*.d
./tests/expected/bubble_sort.d
./tests/expected/cls.d
./tests/expected/fib.d
./tests/expected/import_tests.d
./tests/expected/classes.d
./tests/expected/dict.d
./tests/expected/hello_world.d
./tests/expected/nested_dict.d


I haven't created PR to be merged into the main branch, since 
it's better to pass all the tests.

All the remaining work is to make Python's specific feature (e.g. 
async), library (e.g. complex number, NamedTemporaryFile) work in 
D. There are many things need to be done, if you have time, you 
can pick up from my fork, and work from there. (E.g. you can 
create PR to my branch, and when everything is ready, we submit 
to the main py2many all together).


HTH.
