I know that D is "the best language in the world" and anyone who 
points out serious flaws is a heretic. But thanks for pointing it

I used D for years. Got cured though. I think you get it only 
once. After that, you are immune.

In other words, a mess of dependencies.

There are loads of D users who dislike dub (I always used it for 
convenience though). I don't know if it's dub itself or just the 
fact that those who dislike it won't accept anything but make 
files. I never cared, tbh. The docs used to be hard to read, 
though, I don't know if that has improved.

To be clear, dub is NOT "D's ecosystem", it's a tiny part of it, 
and most issues are not related to dub but to broken packages due 
to compiler upgrades and other toolchains. For example, is there 
a tool to streamline D integration into Android and iOS (cf. 
Nim)? Where are the plugins for the major IDEs? D doesn't care, 
but it sure won't scale this way.
