There are no such variants. They could be added, but they don't currently 
exist.

trim and strip are the same thing. Having both would be bad design. It's 
understandable if you were looking for trim first, since a library could go 
with either name, and you probably have seen others using trim, but we chose 
strip, and we're not going to have both.

chompPrefix is chompLeft. And no, _neither_ is the delimiter variant of 
stripLeft or stripRight. stripRight with an arbitrary delimiter would remove 
all instances of that delimiter from the right-hand side of the array (and 
that delimiter would have to be a single character), whereas chomp takes a 
substring and removes _exactly_ that substring. The same would go for 
stripLeft and chompPrefix.

They could be added.
