* fixes #18235 - proc annotation type macro sym leak - also fixed a typo - proc annotations guard symbol exports with shadow scopes - symbol handling is shadow scope aware * test for exporting an existing unexported sym this one is for my homie alaviss. * Special handling not needed in semProcAnnotation * Testcasing * [skip ci] clean-up and add some more comments * [skip ci] rm trailing whitespace Co-authored-by: Clyybber <darkmine956@gmail.com>
