That's not how I read the spec. As I read it, it will evaluate to the
same string as 'abc"', followed by a nonsensical def""" which should
trigger a syntax error.

No it doesn't. That is three quotes followed by an escaped quote
followed by two quotes (which do not end the triply quoted string), as
I read the spec.

Looks to be so, yeah.

Seems so to me.
