> common code often has constructs along the lines of:
> String r = ((v != null) ? v : "default");
> wouldnt this be better handled by a simple operator ?
> groovy has "?:" (http://www.groovy-lang.org/operators.html#_elvis_operator)
> like:
> def r = (v ?: 'default');
> and php 7 now has '??'
> (http://php.net/manual/en/migration70.new-features.php#migration70.new-features.null-coalesce-op)
> like:
> $r = ($v ?? 'default');
