More complicated transforms may ''require'' an explicit schwartzian transform routine. An example of where an explicit transform is desirable is the <code>schwartzian()</code> routine in the [[P-value_correction#Raku|Raku entry for the P-value_correction task]]. |

Arrays have a <code>sort_by</code> method which does a Schwartzian transform. |

<syntaxhighlight lang="ruby">p "Rosetta Code is a programming chrestomathy site".split.sort_by(&:size) |
|||
# sort by word-size, then lexical: |
|||
str = "Rosetta Code is a programming chrestomathy site seven extra words added to this demo" |
|||
p str.split.sort_by{|word| [word.size, word] |
|||
</syntaxhighlight> |
|||
{{out}} |
|||
<pre>["a", "is", "Code", "site", "Rosetta", "programming", "chrestomathy"] |
|||
["a", "is", "to", "Code", "demo", "site", "this", "added", "extra", "seven", "words", "Rosetta", "programming", "chrestomathy"] |
