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 = <foo>;
   fun2 y = <bar>;
   ...

it's really the same as if it was:

   let fun1 x = <foo>
   in let fun2 y = <bar>;
      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.
