Support for the coalesce operator

Coder version 7.x (and I suspect version 8.x) does not support the coalesce (??) operator introduced in php7.

Would it be problematic for support to be introduced?

$name = $firstName ?? $username ?? $placeholder ?? “Guest”;

Notes:

Support is only lacking because it treats ?? as a single ? and expects a space to be on either side and in the event of coalesce operator is used that rule explicitly becomes invalid.
