The reason is that the semantic overrides are set for the entire compilation (they are stored in SemanticsContext, which is shared between all program units).

This may be somewhat unexpected, but is probably better than making it per-program-unit. Doing so would require adding a program unit parameter to the `IsClauseAllowedOnDirective` function, which would be rather bizarre.
