Pretty sure there's a way to change a struct's layout if it's being used in compile time. All that needs to be done is just bring the fields out of the union when used in CTFE.

Apparently this isn't possible.

There are two ways of fixing this

1. remove the small string optimization from Grapheme
2. have byGrapheme return a specialized type of Grapheme that doesn't have SSO

Or

3. Create a special function byGraphemeCTFE which is a range of CTFEGraphemes. That way there's no performance regression
