onlineapp.d(8): Error: declaration onlineapp.main.S is already defined in another scope in main at line 5

It should be possible to do this as they are in different scopes and should've be different than declaring a variable in different scopes.

Issue 18266 was resolved but only "half" fixed - i.e. the ICE part. So I'm creating this one to keep track of the other half of that issue.
