It could have an effect if a was a struct/class via operator
overloads. But in this case it should probably be a bug.

Opposed to Java, D's member variables are static initialised.
Is there any documentation about this? I find it unexpected.

I often use a pattern of having const ref struct parameters (as
in C++) but this doesn't work in the case of rvalues. The
workaround of defining an overload that calls its own name is
terrible. I understand there was a DIP 1016 by Manu asking for
this case to work. As far as I can tell, this

Hmmm I know about move semantics, and C++11 etc. I just don't
know how related all that is to my original question. :)

The only reason C# allows this is for interop or code generation
for other languages that use the same keyword. For
