There's nothing about purity enforcement there. In fact, I tried
using pure unit tests yesterday with std.experimental.testing
and couldn't. The compiler inferred the functions to not be
pure.
I tried adding pure to them and descended into a madness of
adding pure all over phobos until I got fed up. It seems to be
something to do with `format` not being pure, I have no idea
why. It really should be.
There are various unit tests in Phobos that are annotated with
@pure, @nogc, nothrow, etc. to test that those attributes will be
inferred by the compiler. In light of that, this could pose a
problem.
