Add support for overriding functions #2158
Description
The language server currently doesn't automatically infer types when overriding functions.
Example of the desired behavior:
---@class FooClass = { ---@return FooClass new = function() -- create an instance of FooClass end ---@param foo number ---@param bar string foo_callback = function(self, foo, bar) end } test = FooClass.new() -- automatically infer types from FooClass:foo_callback function test:foo_callback(foo, bar) -- foo is of type number -- bar is of type string end
