Fixed-size Array Annotation

[kylechui]

Hey all, I noticed that there's a way to denote arrays, i.e. string[]. Is there a way to indicate the size of such an array? For my particular use case, I would like to indicate that a position always comes in a { row, column } pair. For the time being, I've been using this:

---@alias position integer[]

Is there a better way to do this that would better express intent? I've tried stuff like

---@alias position {integer, integer}

But I'm pretty sure that the above syntax interprets the list as an associative array, requiring names for the elements.

You may use ---@alias position {[1]: integer, [2]: integer} for now.

I've tried the above using the following, but it yields no warnings:

It seems to still not detect extra elements, although it does work well for ensuring that the first two elements are integers. Furthermore, the third element can actually be a string or other type, without triggering any warnings.
