Yes, faulty implementations of underlying components can always be a problem. I don't know if this was the case in the situation you describe, but generally speaking, an algorithm that performs concept checks for concepts that it doesn't actually need is just that: faulty. So if (which has not been shown, but anyway) there are algortithm implementations that would not accept proxy_iterator:s because they do over-reaching pre-condition testing, this is a problem with that algorithm, not with the proxy_iterator. But I agree, it's a point well worth keeping in mind, that since the proxy package is designed in a way that may not coincide with many people's expectations, it may possibly run a higher than normal risk of triggering latent bugs in various third-party components. /Christian
