I only found these so far, unfortunately these do not seem as conclusive as I remember (because they usually talk specifically about "functions" and I suspect some functions are considered to be more function-like than other functions):

TDPL, says function arguments are evaluated left-to-right on page 50.

AFAIU both my frontend and SDC went with strict source-order evaluation. That seems like the only sensible generalization of left-to-right function argument evaluation, but perhaps common sense is not so common after all.
