Well, using (E;...) everywhere is tedious. Maybe it makes more sense
to have the slightly more verbose
.iff
.then
.else
so that we can avoid excessive parentheses – the `.then' keyword would
be the sentinel to stop the conditional expression. Alternatively, we
could mandate to always use braces:
.iff ... \{\
.\}
.else \{\
.\}
