I must say I don't know why that is, but FWIW in my local experimental language (Typer) it makes some sense: Typer has no top-level environment, so if a file is defined as: fun1 x = ; fun2 y = ; ... it's really the same as if it was: let fun1 x = in let fun2 y = ; in ... You can still try to cobble up some kind of "list of top-levelish definitions" but it's inevitably a hack. OTOH, LSP could define the set of possible choices as the set of possible "breadcrumbs" info. Stefan
