This is the price we pay for having the semicolon optional after a
statement. The ':' denotes a call, and can be used as a statement by
itself. Therefore, if the previous expression were correct, the following
one should be, too:
But now, if the previous statement was "i=a", we would have
and the interpreter would read this as "i=a(m1*m2):print()" (as it
actually does). I do not know any "elegant" solution to this problem.
