TXR provides a number of sorting functions. <code>sort</code> and <code>nsort</code> (destructive variant) are not stable for vectors and strings, but are stable for lists.
The functions <code>ssort</code> and <code>snsort</code> counterparts are stable for all sequence kinds.
In addition, there are caching variants of all these functions: <code>csort</code>, <code>cnsort</code>, <code>cssort</code> and <code>csnsort</code>. They respectively have the same stability properties as their counterparts without the leading <code>c</code>.
TXR Lisp originally had one sorting function called <code>sort</code>, which was destructive, like the <code>sort</code> in Common Lisp. That function was renamed to <code>nsort</code>, and <code>sort</code> became the name of a non-destructive function. That happened in TXR 238, released in May, 2020.
