There is currently no implicit for aggregates except using `alias
this`. But in your example, it's a construction, not an
Ahh, thanks. Looks like encapsulating the union in a struct with
alias this gets the job done, and removes the need for overloads.
Neat.
struct vec2 {
union {
struct {
float x = 0.0f;
float y = 0.0f;
}

All implict conversions are done using alias this:
