If I remember correctly (and I may well be misremembering), an Algol 68
unit could return a name and not just an expression - i.e.:

    (a | b | c) := y;

or:

    if a then b else c fi := y;

However, I may be getting confused with which language it was.  As I
said, it is not a construction that I regard as particularly clear,
and therefore almost never used it.  I use the expression form very
heavily, in any language that has it, because so many operations are
precisely that construction.
