+is suitable for keeping many short strings in memory. This is similiar
+to how @code{ShortByteString} relates to @code{ByteString}.
+
+The main difference between @code{Text} and @code{ShortText} is that
+@code{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.")
