Is there a way to show that a function can error ?

[LamprosPitsillos]

---@errors
local function foo()
...
if true then error(...)
...

So that later i get a warning if i don't use pcall

local x =  foo() -- WARN
...
local ok,x = pcall(foo) -- OK

There is currently no annotation with described behavior. You could open a feature request instead.

There is an open feature request that asks for a @raises annotation.
