There's a long thread on something similar here:

Here's an even older thread:

In the more recent thread, I suggested that we give strings a dedent method. When called on a literal, the keyhole optimizer may do the dedent at compile time. Whether it does or not is a "quality of implementation" factor.

The idea is to avoid the combinational explosion of yet another string prefix:

    urd'...'  # unicode raw string dedent

while still making string dedents easily discoverable, and with a sufficiently good interpreter, string literals will be dedented at compile time avoiding any runtime cost:
