I do, my complaints is that you're making it needlessly complex.

No, the implicit concatenation is there because Python didn't always
have triple quoted string. Nowadays it's an artifact and triple quoted
string is much preferred. Long dump of text in source code is usually
(or should be) globals constant anyway and you have no problem about
indentation in globals constant. The only ubiquitous place where you
need to put long stream of triple-quoted in non-global is as docstring;
and docstring already handles the problem with indentation.

It's the nature of the text, who cares about extra line breaks or two.
If this string has been for regex, I'd probably care.

I used triple-quote a lot, and I'm very aware of that.

When you have long stream of text and you paste it in source code, it's
usually for one-off scripts that you're too lazy to create a proper file
to read from. You never want to have to do some tedious preprocessing
before you can insert it to the source.

There's never a good reason to insert very long streams of text using
implicit concatenation; not since docstring is here.
