About element1, it is initialized by the out argument at line 71
About element2, vala could warn about assigned but not used yes.

void main () {
        string foo;
        foo = "foo";
}

Do not mark variable as used for simple assignments

Fixes bug 570128.

Things get more complicated for non-simple assignments because they get transformed.
