No, but sys.settrace might.  However, your approach also makes sense.

Module tokenize lets you easily distinguish logical line continuations
(then, tokenize generates token NL for the "nonterminating" newlines)
from ends of logical lines (then, tokenize generates token NEWLINE for
the "terminating" newlines).  That may be all you need, perhaps?
