@nogc conflates "doesn't allocate memory from the GC heap because I don't want my application to use the GC at all" with "doesn't cause GC collection pauses".

The latter can have a @assumenogc annotation that works -- you call GC.disable and GC.enable as appropriate. The former can't.

For whatever reason, I like the idea of annotations behaving like enums. So instead of @gc or @assumenogc, you could have something like @nogc.false or @nogc.assume. You wouldn't add new annotations, just new behavior for existing annotations.
