This is to handle the not-anonymous-but-still-an-expression case where you could use that local name to refer to the type of the expando-thing as a whole. Because it'd be odd if just adding a name to the function expression made this transform stop working.

Is this is for cases like
const f = function g() { }
f.p = 1Does remappedSymbolReferences record g? When would g show up in the declaration emit?
Edit: Looking at the test cases, it's actually g -> f so that when a constructor function g returns g, it serialises as f.
