Type Checking

Expected Behaviour

When a class which is overloaded as a function, if that class is passed as an argument to another function it should be checked as if it is a function if the argument has a function type.

---@param f function
local function call(f) f() end

---@class foo
---@overload fun()
local something = setmetatable({}, {__call = function () end})

call(something) -- <-- Here something should be treated as `fun()`

Actual Behaviour

The type of the class is treated as foo|fun() which results in a warning because foo does not match function.

Reproduction steps

1. Create a class with an overload
2. Pass it to another function which takes a function argument
3. Observe that a warning is produced

Inizia con la riproduzione Lua fornita e traccia il percorso del controllo dei tipi per gli argomenti delle funzioni e le classi sovraccaricate. Il lavoro è completato quando l'esempio non emette più avvisi passando la classe chiamabile a un parametro di tipo funzione, mentre i passaggi di riproduzione continuano a comportarsi correttamente.
