​Then again, similar behavior in python (prefixing a string with r to
qualify it as a 'raw' string) would be completely unintuitive because
backslash behavior is... weird. For example, r"\" is not a valid string.
You can't have a string that's just a backslash just in case it can be
processed as an escape even though raw strings aren't supposed to process
escapes. Some other things are weird... So having blanket "yes, it's really
raw" behavior -might- be unintuitive for people coming from python.

BUT... And this is a massive but... It -would- tie into the discussion that
currently exists for typed literals (something i'm currently mostly
ignorant of and would love to hear more about). Especially since it would
put the qualifier in front of the literal.
