see my previous mails for arguments in favor of accessor functions, but if
people don't agree with that, at the very least both syntaxes should be
supported, because interfaces using properties and interfaces using accessors
can overlap.
take for example a GUI library that uses your proposed properties. a
GUI "list" widget would probably make its list elements available through the
interface of a STL container, so it must support size().
but you'd probably also want a property named "size", if that is how the rest
of the GUI library is designed.
