As I read it, the discussion was entirely about the semantics of the proposed dependency of a function (or procedure) upon an extension. The idea to establish such a dependency using “alter function” came up quite early in the discussion. It seems that establishing it at “create function” time was never considered. Unless anybody corrects me, I’ll conclude that it’s perfectly feasible to establish the dependency at “create function” time. This would meet an obvious niceness goal (symmetry and guessability). It would also increase the possibility for component rule re-use in the presentation of the syntax rules. But I don’t s’pose that the effort of changing anything here would be cost-effective. |
