You probably meant Bar(256) on the right hand side? Then it's a struct
literal.
In any case, even if the produced codes are the same; *I think* the
latter is actually technically default construction, followed by
assignment. Which may involve different operations, depending on the
struct...

I miss that from C++ too. I assumed that there must be reasons related
to D's syntax for not allowing that.
I've settled to this syntax myself, which is effectively the same as
your first above:
auto bar = Bar(256);
