Type Checking

Expected Behaviour

I have a file with two functions that both cast a local variable to a different type. This works perfectly for the first function but fails for the second (or the last if I add more functions).

Actual Behaviour

Error Unknown type conversion variable item (unknown-cast-variable) for the ---@cast item B inside fu().

Reproduction steps

---@alias A table
---@alias B table

---@type table<number, A>
local items = {}

function fu()
  local item = items[1]
  ---@cast item B
end

function bar()
  local item = items[1]
  -- Error appears here:
  ---@cast item B
end

See this for a workaround and more details: #2207
TL;DR: add a newline at the end of the file.

Thanks @PinewoodPip for the quick answer! I didn't search in the discussions 🙈

Is this eof error/quirk planned to be fixed? This is still the case.
