[Feature Request] Ability to use Ternary Operator to select structs #273

Open devshgraphicsprogramming opened 4 months ago

Is your feature request related to a problem? Please describe. Trying to compile the following code: https://godbolt.org/z/9cx4aMca1

Which "just works" in C++ https://godbolt.org/z/7adWze3dn

Describe the solution you'd like Just being able to ? between two variables of the same type.

Describe alternatives you've considered Right now I have to pack unpack structs when I want to do that, but its cumbersome.

Additional context Conditional swaps for FFTs and Bitonic Merge sorts are hard to make without this.

This is something we should look into enabling, but it does require a language change so we need to think more carefully about how to approach this.
