The usual D idiom is to write:

mystruct_t myfunc() {
return mystruct_t(val1, val2);
}

Unfortunately, AFAIK at this time there's no way to write field names as
well, so you'll have to rely on the struct's field order or the ctor's
parameter order.  (But I could be wrong.)

Returning constant / literal struct value (pod)

[Cecil Ward via Digitalmars-d-learn]

Can we return a literal struct value straight from a return 
statement ?


ie something like
mystruct_t myfunc()
{ // ... blah
return { field1: val1, field2: val2; };
}
assuming that the return type is defined suitably, and the struct 
is just a C struct, plain-old-data (ie not a C++-like class).


I've had to set up a throwaway const item, initialised, and then 
had to return that.
