https://issues.dlang.org/show_bug.cgi?id=1985 --- Comment #11 from anonymous4 --- I think it's better to replace import expression with intrinsic, say, importText (like std.file.readText). This will also reduce grammar complexity and remove second and rarely used

https://issues.dlang.org/show_bug.cgi?id=17448 --- Comment #26 from Eyal --- What solution is there for this use-case then? We need objects to register themselves (i.e: set out-of-scope pointers to point at them) and RAII-wise have them de-register themselves. While they are

Fetch and pre-build dub dependencies

I have a Dockerfile to build a vibe.d project. Docker has a nice caching system so it continues building the docker image from the step where it's needed when something changes. This is typically at the step of adding my source files, then building the binary. The problem is that fetching and
