Revisit iteration scope facets for "funk" and "funk name"

Yeah so the issue is that we don't necessarily want the iteration scope for functions to always include blocks. For example, that's not what we do in typescript. I added this as a catch-all so that I could include blocks for css. Might be worth discussing?

update from meet-up:

• Let's leave it for now
• In the future, one way forward is to support language-specific facets and then add namedFunction.iteration.block as a css-specific facet
