--- Comment #1 from Johannes Pfau <johannespfau at gmail.com> ---
A long standing issue. Function arguments should be LTR. Pull request is
available, but blocked as it needs a final decision by Walter or Andrei for the
evaluation order of (all kinds of) assign expressions.

Currently blocked PR:

BTW: The spec doesn't really contradict itself:

"_are_ evaluated in an implementation-defined order: ... function arguments""
is what _does_ happen.

"The evaluation order of function arguments is _defined_ to be left to right."
is what _should_ happen.

"Note that dmd currently does not comply with left to right evaluation of
function arguments."
explains the difference.
