This only happens when building the project as a shared

solutions? Thanks in advance.
This is a known issue:

Will be fixed in LDC 1.31.

Re: Why not allow elementwise operations on tuples?

I was wondering if there's a strong reason behind not implementing elementwise operations on tuples? Say, I've decided to store 2d points in a `Tuple!(int, int)`. It would be convenient to just write `a + b` to yield another `Tuple!(int, int)`. I've written a Vec type that implements precisely this, using tuples behind the scenes as the implementation, and operator overloading to allow nice syntax for vector arithmetic. Yeah, that's clear that such an implementation is rather straightforward. Although, I'm a bit confused with your implementation - 1. it doesn't seem to use tuples behind the scenes despite your claim (it uses static array) 2. `alias impl this;` introduces some unexpected interactions (e.g. `~` and `toString` are "intercepted" by the array implementation and yield "wrong" results). Anyway, my original question was primarily about reasoning - why there's no implementation specifically for `std.Tuple`? If it's a "feature, not a bug" - what's the best way to provide an implementation on the client side?
