Why are you doing the replacement top/down rather than bottom

What would be the alternative? -- Andrei
Doing the replacement bottom up :
a = a++;
a += { auto olda = a; a = a + 1; return olda; }();
a = cast(typeof(a)) (a + { auto olda = a; a = a + 1; return olda;
}());
Other code transformation do not require a function call to take
place, so why would this require one (which force eager
evaluation of parameters) ?
That is also inconsistent with LTR evaluation. On the other hand,
that would make behavior consistent with what opOpAssign would
give, so why not.
