Hence  a local function can't be passed anywhere.

You do know that anonymous functions can use variables contained in the
function they are defined in as well? Also local functions can be passed
around in Delphi and recent FPC functions, but you shouldn't call them once
the containing function as exited (so for local callbacks they are useable).
