Unintentionally global variables stat and ret in async_lib?

[bluss]

It looks like stat and ret should be local in this code and not global.

This is a common mistake in lua that happens easily I guess. Found by lua language server autocomplete.

To make them local would make them encapsulated, and you avoid risk - people using the unintentionally used variables, or overwriting people's globals.

	M.protected = async(function(future)
	local tx, rx = M.channel.oneshot()
	stat, ret = pcall(future, tx)
	if stat == true then
	return stat, await(rx())
	else
	return stat, ret
	end
	end)
