In this particular context, does this error message not mean: I didn't
find a concatenate method in the 'str' class that has an 'int' as
argument? So that's not exactly about typing IMO.

Coercion would be that either x or y would be coerced into the other
type before performing the operation. That would depend on the
operator (i.e. '+' would determine this rule).
