Answer 1

You have used a pre c++11 standard compiler. The older standard had a problem letting the parser disambiguate a pair of closing angle brackets >> used in a nested template type specifier, from the operator>>(). Thus you had to write a space between them.

The samples like >>> or >>* are falling under a different case for the old parsers, thus they work without error message.

_{I have to admit, I don't actually know what exactly was done in the c++11 (the current) standards definitions, that this situation can be clearly disambiguated by a c++11 compliant parser.}
