its possible and good to use \ and \z for multiline interpolated strings today

[xHeptc]

local str = [[
%s has joined the chat!
%s says hello world!
]]

local str = string.format(str, "John", "John")
print(str)

Why not just do this? (Yes it's string formatting, but you can still have the same output, with a little overhead perhaps)

[Kampfkarren]

You definitely can't do `[[ or [[` since both are backwards incompatible
