Is this comment still needed? It seems to work that way now.

Removed.

-macro GLOBAL_PRIVATE(name) = (%CreateGlobalPrivateOwnSymbol(name));
-macro NEW_PRIVATE_OWN(name) = (%CreatePrivateOwnSymbol(name));
+macro GLOBAL_PRIVATE(name) = (%CreateGlobalPrivateSymbol(name));
+macro NEW_PRIVATE_OWN(name) = (%CreatePrivateSymbol(name));

[rossberg, 2015/06/15 12:09:11]

Rename this to NEW_PRIVATE

[wingo, 2015/06/16 07:09:45]

Done.
