Order of eval in struct keys

[roidel...@gmail.com]

Hi,

Reading https://golang.org/ref/spec#Order_of_evaluation does not explain if the order of evaluation in struct is defined.

see https://play.golang.org/p/tjCrTI77UwZ

Is that behavior guaranteed?

Thanks

There is no guarantee about the order of evaluation within a composite
literal in general. However, there is a guarantee that all function
calls will be evaluated in left to right order in any expression,
including a composite literal. So while you didn't actually say what
you expect, I think that your example is guaranteed to behave the same
in any Go implementation.
