Re^2: Check if one of the array elements is not empty

And the nice thing about List::MoreUtils::any is

that it will return as soon as it found a "match" in the array and does not have to run through all elements as grep does;
it can take any function or subroutine as an argument to match, not only a regex.

ad 1. on other side, `grep` in scalar content returns number of matching elements, so you can do tests like "at least N elements match" ad 2. same you can do with `grep`	[reply] [d/l] [select]
