AFAIK dmd supports the `-cov` flag since quite some time, so I
would be interested why there's no code coverage bot. There
also seems to exist at least two external platforms that allow
such code coverage analyzing [1, 2]. Is this already on your
roadmap?

[2] https://github.com/ColdenCullen/doveralls/issues/16
Anyways it seems pretty easy to hack something quick&dirty
together that could be pretty helpful:
Yep. The difficulties are:
1. Getting data off the autotester. Currently it's nearly
impossible, as is making any changes to it.

2. Collating data from multiple platforms, as there is a lot of
platform-specific code in e.g. std.stdio, std.file, and most of
Druntime.
Okay I see that for the long run we need a better way to handle
the testing infrastructure :/
Can't we focus for the near future on getting a simple Phobos
coverage tester that just compares the coverage of all files
changes like your DAutoTest?
With this approach we can still prevent regression and show
improvements.
