description:         This package provides the 'ShortText' type which is suitable for keeping many short strings in memory. This is similiar to how 'ShortByteString' relates to 'ByteString'.
                     .
                     The main difference between 'Text' and 'ShortText' is that 'ShortText' uses UTF-8 instead of UTF-16 internally and also doesn't support zero-copy slicing (thereby saving 2 words). Consequently, the memory footprint of a (boxed) 'ShortText' value is 4 words (2 words when unboxed) plus the length of the UTF-8 encoded payload.
