The filter function is non-intuitive

It also prevents the (ground) coffee from getting through. Filtering is so ambiguous.

We could just rename filter to generalized_coffee in Julia 2.0 and be done with it.

Iā€™ve always said, the one thing Iā€™m missing from julia is that it doesnā€™t make my coffee. If we can get this fixed in 2.0, that would be excellent :+1:

Has someone already filed an issue for this?

It should at least give a 418 error.

Apart from this not being changed in Julia and marked as ā€œsolvedā€ I think this is personal preference. To you it might be counter intuitive, but to me it functions exactly as I expect it to be.

In music and in medicine (and more generally signal processing) a high-pass filter lets the high frequencies through, a low-pass filter lets the low frequencies through and a band-pass filter lets a specific band of frequencies through. If you ask me what I expect from an odd-number filter (the way you have written it), I would be surprised not to get the odd numbers :slight_smile:.

Iā€™ll be repeating the sentiment of other replies, but it really is a matter of personal experience.

In astronomy filters are defined by the frequencies they let through, so itā€™s perfectly intuitive for me.
