I wouldn't think that this is worth it. As Tim mentioned elsewhere, for
properties that need to be read/written in a time-critical fashion, it's
best to add specific getters/setters. GTK already does this in many
places (often for convenience, not for performance reasons), so I don't
see how this is a huge burden.
Regardless, have you done any benchmarking? You might find the
performance issues to be negligible. And you might not. But throwing
around statements like "it's definitely much slower" is meaningless
without numbers.

If it needs a preprocessor, it's not "plain C++".
