Re: [Algorithms] How to get 3dvector largest coordinate index?

[Conor S. <bor...@ya...>]

Unions are for variants (and trix are for kids!). They can be used to implement tagged variant types and even full algebraic data types (if you put a union inside of another construct), as well as the lower level uses (such as saving storage space, usually through some sort of implicit tagging).  

Cheers,
Conor

if cast-through-union violates the standard, then why are unions in the language? isn't storing bytes and interpreting them as different types what unions are for?
