Maybe this is also a good place to discuss potential design flaws?

JCW: The choice of '[[' and ']]' as multi-line string delimeters seems like a better one than Python's '"""' at both ends, for example, since it allows nesting. So the following will work as expected:

    a = [[ b = [[ c ]] ]]

And even this will, no doubt:

    a = [[b=[[c]]]]

But all is not well, the following will not parse as expected:

    a = [[table[1]]]

With a non-symmetric set, this would not happen (i.e. not just doubled square brackets).

Side issue: wouldn't it be nice if gsub's '%b()' syntax also allowed multi-character delimiters, such as '[[' + ']]', or '/*' and '*/'? It would need some syntax, one option is to disallow using digits, then 1..9 would indicate the size of the token, e.g. "%b2/*2*/" (no, it's not very pretty...).
