3.12.5 Constructor Functions
"The semantics of the constructor function T($arg) are defined to be equivalent
to the expression ($arg cast as T?)."

Please clarify whether this is talking about the semantics of the function or
the semantics of a *call* to the function. If the former, then a call to the
function has the usual call-related semantics (including the function
conversion rules of section 3.1.5). If the latter, the equivalence bypasses the
usual call-related semantics.

(Mind you, I haven't found a case where the two interpretations lead to
different outcomes.)
