Changes in const correctness and some deprecated functions:

/home/simendsjo/code/vibe/vibe.d/bin/../source/vibe/vpm/dependency.d(152): Error: function vibe.vpm.dependency.Dependency.opEquals does not override any function, did you mean 'vibe.vpm.dependency.Dependency.opEquals'

Line 152 needs to both be const and take a const ref as parameter. That doesn't work on 2.059 though..

I've used std.compiler now to (hopefully, didn't test 2.060 yet) make both work. I'll remove the 2.059 code around the time when 2.061 comes out.

But 2.060 seems to be an exceptionally promising release.. maybe the most important release since the beginning of the 2.x branch :)

I'll test when I get home tonight.

It's a promising release indeed. Perhaps we can finally start using const to a larger degree.
D is already such a nice language, but it'll really shine when all features are implemented and things gets stable.
Still just playing around with D2 as I was really bitten by the instability of D1 :(

Works, thanks.

These changes was rolled back in dmd...
