Yes you are right. If closing triple quote is on a separate line , I
can use the last line
contents and extract it from previous lines. I should have remembered that
trick and it is cool actually. So technically I can do it.
So my point was that it would be cool to have a dedicated statement for this and
so it works on parser level plus would look cleaner (no closing
quotes), and no need to care
about  escaping of """ sequence if it appears inside the string, but I
think that would be impossible
without the parser knowing the indent method in advance.
