fn into(self) -> Expr

If a function has a function name, it may be called recursively. We use the named expression to hoist the function name internally Therefore, its recursive calls refer to the correct identity.

Else if a function has a binding name, it may be called recursively as well. But it refer the binding name which exist the outer scope. It is safe to using anonymous expression wrapper.

Optimization: A function without a name cannot be recursively referenced by Ident. It’s safe to return the expr without wrapper if the params.len is 0.
