Good one. Any plans to push SumType as a replacement of
Phobo's Algebraic?
Phobos is essentially dead/frozen (feature-wise). Though if
someone ever manages to get v2 of the ground, SumType would be
the obvious choice.
Anyhow, currently we would have to name it differently (e.g.
dts - https://github.com/wilzbach/dts). Maybe the upcoming SAoC
project will change this and allow multiple versions of a
library to co-exist in a binary.
I actually would like to submit SumType to Phobos, albeit as an
alternative to Algebraic rather than a replacement for it. Given
how dramatic the improvement is, I think it's worth the
awkwardness of having two sum type implementations in the
standard library.
Currently, the main thing blocking me is bugzilla issue #19458
[1], which (for somewhat complicated reasons [2]) makes it
impossible for SumType to support members with @disabled and
non-const opEquals overloads.
