Hi, HAMT is a very useful immutable mapping type. Currently CPython use it internally to implement contextvar. Considering immutable data structure is very useful I hope we can make it available to python script(maybe via collections module).
Immutable data structures are fundamental parts of our project. Currently we use a full-featured python immutable data library called pyrsistent. Pyrsistent is very powerful, however the map type in it is implemented in python script not in C. It becomes slow when the data set is relatively large. On the other hand, CPython now already has an immutable mapping type in it. I think maybe it’s a good idea to make it public? Many projects can benefit from it I believe. Here is a talk given by the author of javascript immutable-js library explain why immutable data structures are powerful: https://www.youtube.com/watch?v=I7IdS-PbEgI Pyristent: https://github.com/tobgu/pyrsistent What do you think?
