how to concat in a multi line string lua code example

Example: lua multiline string

answer = [[
Multiline strings in Lua do not interpret escape sequences like \n.

When running over multiple lines the enters are included, only
when the first character is a newline it is ignored.

These strings can be nested with = signs between the brackets like 
multiline comments: [=[This would be a valid string too]=].
]] --> multiline string with trailing newline
