If we’re assuming you’re totally new to Swift and the first thing you do is go
looking for a map function, then you’d still need to double check exactly what
you’re doing anyway (how to write the closure etc.) so I’m not sure a few extra
letters is going to make a meaningful difference in speed as you’ll be double
checking documentation anyway to be sure you use the function correctly.
Meanwhile if you’ve been through a few Swift tutorials or whatever with the
current API guidelines adhered to, then you should be used to, or at least
aware of, the form for mutating vs non-mutating method names, so seeing mapped
shouldn't cause much pause either.
I just don’t think it can possibly have a meaningful impact on time; it’s not
as if developers are going to be off wandering the streets with their whole
world turned upside-down, unable to figure out what to do with themselves
because they’re suddenly unable to find a map method, only some bewildering,
alien method named “mapped” that could be anything.
I’ll grant that switching to mapped is relatively minor, but if everything else
is named following one set of rules I think a better case needs to be made for
why some functions should have their own set of rules, especially if it amounts
to “that’s what others call it”, in particular if those others call it that
because that’s what others call it and so-on ;)
