Long brackets litterals (with [[...]] or [=[...]=] or with longer matching sequences of "=") are very rarely used (unlike long comments where "[[...]]" or "[=[...]=]" or al. immediately follows "--")

Actually I use long strings as the only argument of a function quite
often when quoting shell command line, e.g.

os.execute[[ grep 'blabla$' > "my file.txt" ]]

For me, they work quite well, e.g. I can change

print[[ debug bla bla ]]
...
print[[ debug bla bla ]]

with

--[=[
print[[ debug bla bla ]]
...
print[[ debug bla bla ]]
--]=]
