Shouldn't it be mentioned then in the docs that this works for statically sized arrays and that in that case it copies contents?

Well, I confess that I don't know why you would ever have thought that

s = t;

wouldn't work. The only mutable types that can't be assigned to like this are the ones that have disabled assignment or copying (which would only be certain structs).

And I thought that the spec made it clear that static arrays were value types, in which case the behavior of

s = t;

should be obvious. So, I would have thought that it would be clear enough as-is, but clearly, it wasn't for you. So, I don't know. We do want the spec to be clear, but it would also be bad to add a bunch of redundant information in an attempt to be clearer. I'd have to go digging through the spec though to give any concrete suggestions on how to improve this though.

Hi Jonathan!

Probably this entry in https://dlang.org/spec/arrays.html#usage confused me a bit.

int[3] s;
s = ...;   // error, since s is a compiled in static
           // reference to an array.

Thanks for your help!
