net.server_epoll: Optimize concatenation of exactly 2 buffer chunks Saves a function call. I forget if I measured this kind of thing but IIRC infix concatenation is faster than a function call up to some number of items, but let's stop at 2 here.

local type renderer = function (string, { string : any }) : string
local type filter = function (string, any) : string
local record lib
	new : function (string, string, funcs : { string : filter }) : renderer
end
return lib
