It is indeed rather convoluted. How exactly is this better than [**[ ... ]**] (bearing in mind that there can be zero stars)?

I don't know if it is better, I don't claim it, it is just another proposal. Perhaps it can seems more "natural" to those already using HereDoc in other languages. Note it still go against the ease of syntax-highlighting, but I suppose it is the price to pay to enclose arbitrary strings.

My rules can simplified by removing the exception of [[<nl> and writing [a-zA-Z_]* instead of +. It includes the legacy form and the HereDoc in an unique rule.

That makes three rules:
- one-liners: s = [[Foo Gah Bar]]

- legacy form: s = [[Foo Gah
Bar Whatever]]

- HereDoc form: s = [[T2
Foo Gah Bar
a = b[c[d]]

or: s = [[
Foo Gah Bar
a = b[c[d]]


s = [[__
pfff = [[abc def

Again, this is just a proposal, and of course the final word will go to Lua authors, which probably will just keep the [**[ ... ]**] form, which is fine for me, actually.

Note for the pain to type multiple [ and ]: I share this view, since I have a French keyboard with the same problem (~{[\@]} are hard to type, to give only frequent chars), but I believe that if you have a good editor (scriptable?), or some good utility (like abbreviation expander), the pain can be easily reduced.
