ref2491's original code is valid, but doesn't have the intended meaning.
`e => {foo(e);}` is the same as `(e) {return () {foo(e);};}`, i.e. a
(unary) function that returns a (nullary) delegate. Calling it does not
run foo. In contrast, calling this runs foo: `e => foo(e)`.

in a multiline statement, i believe you must use :
arr.each!((ref e) {
writeln(e);
++e;
})
"=>" is for oneliner
though i don"t understand why it fails silently ??

Ok, Thanks ! :-)
