escape double-square brackets

[BioHazard]

In the following array, one of the items (blue) has double-square brackets:

t = [[
red
orange
[[blue]]
pink
green
]]

print (t)

How would I instruct Lua to escape those brackets in such an instance?

You can do this, which you might find very useful:

t = [=[
red
orange
[[blue]]
pink
green
]=]

print (t)

You can even keep adding equal signs, however I'm not sure if 5.1 supports this too. I do believe so:

t = [=======[
red
orange
[[blue]]
pink
green
]=======]

print (t)

Definitely useful to know.
Thanks very much, IP.
