This will rebind both a and b. In order to be correct, it MUST happen
in two phases: first calculate the right side, then do the rebind to
the names on the left side.
"rebind to the names" -> "rebind the names found on the left side, to
the objects calculated from the expressions on the right side".
I strongly feel that if such an assignment is not atomic for "a,b =
b,a" then int wont be atomic for "a+=b" or eveb "a=b" or any other
assignment.
"int" -> "it"
"eveb" -> "even"
The immutable object itself will never change state, so it is thread
safe. The problem is not with the object, but the dictionary which
holds the name 'b' and 'a' and 'st' in your example.
"The problem is not with the object" -> "The problem is not with THAT
object".
Wanted to answer too quickly. :-( Sorry.
