But keeping a reference to a temporary would not work because the life
of that temporary ends by the end of that expression (practically, at
An option is to allocate the object dynamically with new (and store
DListOfA* in the associative array). Then the GC would keep it alive as
long its pointer was in the associative arrray.
But a better option is to just forget about it because D already takes
care of rvalues by blitting (bit-level copying) them by default.
Everything just works... :) It is not expensive either. For example,
your struct is very cheap to copy.
But I am probably missing the reason why you want a ref there. Perhaps
there are even better options.
