OK, I see, so Java would also be weakly typed because the expression
"hello" + e would call toString() on e implicitly.

It's a fait accompli.  Wise people tend to format their numbers
explicitly, but it would be pedantic to insist on it always.

Implicit conversion of strings to numbers to a + b strikes me as not
