Is this information going to be different? Ever since we added `macros.getType` we had more efficient ways to produce serialization code, it's not a big loss (IMHO, I never use it), there are also third party modules that do what `marshal.nim` does, but better. > Will we have to use new language constructs like sink and lent, whatever they > mean? You don't have to use them but they also improve the clarity of the code, I don't consider them hacks to gain more speed. `lent T` means "I'm providing a readonly view into the data I'm owning" (get, [] accessors), `sink T` means "I'm storing the passed data permanently in a collection". > Is this a huge change for Nim under the hood or is just yet another gc option? It's a huge change under the hood and also "yet another gc option". For now. I hope to make it the only "GC" that survives in the long term.
