A "d" prefix to do textwrap.dedent is something I wished for a long time.
It's like the "f" one: we already can do it, be hell is it convenient to
have a shortcut.
This is especially if, like me, you take a lot of care in the error
messages you give to the user. I write a LOT of them, very long, very
descriptive, and I have to either import textwrap or play the
concatenation game.
Having a str.dedent() method would be nice, but the d prefix has the
huge advantage to be able to dedent on parsing, and hence be more
performant.
