When is fuzzy-completion-set called with a non-simple string?

[phmarek]

When deserializing data via non-default means -- eg. YASON may (in some cases) return non-simple strings.

Also, I'm using that function to provide completion in a web-interface, and depending on how the string gets built it might not be simple.

As it's a swank internal requirement that the string must be simple, I guess this interface is the right place to ensure it.

I wouldn't say that swank provides any interface beyond what slime uses.
