Haha... in this case you want to actually just drop `auto` completely.

Yes, D works on the major desktop platforms easily. There isn't
an ANSI standard but there's just one D language.
A friend of mine asked me a question today if D is multiplatform
I particularly believe it is but I wanted to know the opinion of
who has already developed the most time in it and even of the
developers because I looked for some cisa on the net about such
subject and did not find anything that

LDC does respect explicit type-alignments when allocating

align(n) on the outside of a struct will pad the struct as a

This code compiles with 2.071, but not with 2.072 nor 2.073:
```
struct S {

auto ref foo() @safe {

auto bar() @safe {

It's not assigning data to a slice, but adding elements to it: It *may*
spawn off a new array. You can use .capacity

For completeness, D's 'auto' does not have the same meaning as C++'s
auto. Wait... it actually has! :) But with the meaning of the 'auto'
