@333fred Do you know by any chance whether discriminated unions will be ready for C#10?
The last couple of LDM notes did not really seem to mention the topic and I was wondering what the current state of progress on discr. unions is.....

[Unknown6656]

Oh no :(((
I've been looking forward to discriminated unions ever since the initial proposal in C#6.

I've got Mads "official" confirmation that discriminated unions will not make it into C#10: https://twitter.com/MadsTorgersen/status/1387079125676875776

So sad. I really hope they can work it out for DUs to make it into C# 11, then. If there's one thing I miss from my short trip to functional languages is DUs.
