If any is not given a predicate, it defaults to just checking

rather odd way to write the code and will be less efficient
unless the optimizer manages to optimize away the extra work
involved with having map.
However, in general, with D, you're not going to find that
there is only one way to do things. There are going to tend to
be many different approaches to solve the same problem. D code
is often simple because of the powerful language constructs and
standard library, but it makes no attempt to make it so that
there's only one way to do things - especially when you start
combining stuff to do whatever it is you're trying to do.

Maybe one of these methods can be made 'official' or 'idiomatic':
any!pred(ss);
ss.any!pred();
ss.any!pred;
This will reduce learning burden on beginners.
