interesting syntax ("string" .. ...)

[Mildred <ml.mildred593@...>]

Hi,

I just found an interesting syntax ... here is my code :

local log_level = 5
function log(level, ...)
	if log_level >= level then
		return print("[ "..level.." ] " .. ...)
	end
end

The interesting code is : “.. ...”
It concatenates the string "[ "..level.." ] " with the first string
in ... list

Note that it does not work without spaces (“.....”)

Just a question : it it a valid syntax ?

Mildred
