Link to spec please?  If what you say is true, that sounds like an error
in the spec.  Walter has said many times that evaluation order in D is
left to right, unless otherwise indicated. Having it unspecified just
leads to a huge can o' worms.

Exactly, this is why Walter is against having unspecific order of
execution.  This supposed "optimization opportunity" leads to far more
trouble than it's worth.
