Well, if I'm not inventing capabilities, in C the syntax is fairly
direct (and forgive that with several dozen languages mixed in my head I
cannot write any one correctly without manual in lap, which I don't have
these days):

if
(
  (
    aSomestructTypedVariable =
      aSomestructReturningFunction
      (
        lots,
        of,
        parms
      )
  ).booleanPart
)
{
  usefulVal = somestruct.usefulPart;
}

Does Ada support a similar "assignment en passant" mechanism?

xanthian.

(Does C return structures, for that matter?)
