I recall having seen an example of using some D magic (via mixin
perhaps?) to realize tuple destructuring in assignments like
magic(first, _, second) = expression.findSplit(separator);
somewhere. But I can't seem to find it right now.
References anyone?
BTW :I'm aware of Kenjis PR, which

Can this be solved with a mixin somehow?
To clarify, I want to be able to write
let(first, _, second) = expression.findSplit(separator);
without having to first declare `first`, `_` and `second`.
I'm guessing the closest thing we

Correction: I believe it must look like

I added support for auto, const and immutable declarations at

And support for ignoring `_` as a variable as:

mixin let!q{ c, _,
