a = b = 1 just syntactic sugar?

I see. In Grammar/Grammar, I have

simple_stmt: small_stmt (';' small_stmt)* [';'] NEWLINE

Using grammar.txt instead, your specification is still
underspecified. You mention some detection of ambiguities. How exactly
would that work? For example, what is the meaning of

a = lambda b : return b > 0

Also, what is the meaning of the statements inside the lambda
expression, in particular of assignment and return statements?

E.g. if I have

x = lambda b:c=3

what happens if I invoke x(4)? What if x is

x = lambda c:c=3

What is the meaning of continue inside lambda?
