I don't know if there is a plan now to replace it, I'd guess not. 
I am not aware of any reason why `alias this` should be removed 
(for structs at least). If there was a replacement feature, it 
should be capable of everything `alias this` can currently do 
IMO, so that there would be an upgrade path.

There was a project item to 'Explore a replacement for alias 
this':
https://github.com/orgs/dlang/projects/22/views/1?pane=issue&itemId=29572699

Though that was part of a set which was closed (maybe last year).
