explicit functions that are not candidates. It's not always obvious that the reason a conversion was not possible is because the function you wanted to call is 'explicit', so explicitly say if that's the case. It would be nice to rank the explicit candidates higher in the diagnostic if an implicit conversion sequence exists for their arguments, but unfortunately we can't determine that without potentially triggering non-immediate-context errors that we're not permitted to produce.
