I don’t want to be discouraging of good work, but D is not lacking in great features, it is lacking in its implementation of the basics.
I have come to believe over several years working in D, managing work in D at some scale (10s of devs, not 100s) & advocating for D that the foundations are shaky and crumbly and need work.
While it is not possible to implement a struct as drop-in replacement for a built in slice, while template symbol emission bugs keep happening[1], while the built in AAs are not in great shape (and the signature of toHash is a PITA), while the compiler is a huge memory hog and compile times for templates get wild, while speculative compilation results somehow go wrong and leak in to the non-speculative parts of compilation (e.g. https://issues.dlang.org/show_bug.cgi?id=19545), while syntax changes happen without enough noise (so even basic tooling ends up breaking), while shared and property and synchronised classes and so on sit in poor and/or incomplete shape, while delegate contexts still have qualifier problems[2]…
Why would the limited resources available be focused on a built-in sum type?
You should make a list sort by importance.
