To Simon: Fair. It is indeed a little odd that C++ committee decides to put
one before but one after the signature. Only that you might want to write
it in the style guide; otherwise, both styles will appear in the future.
To Mark: I said {the use of both is redundant}, not {one of them is
redundant}. But if this scenario happens in code reviewing, I'd accept your
comment that the original statement isn't in its most exact form and I
should say "virtual is redundant when using virtual + override".
