<P>Without knowing about this node, I wrote
[id://340164].
<P>It is not a complete obfu-engine, just lists compact encoding of the first few numbers. For some punctation chars, it gives a bit shorter encoding than yours (while it has longer ones for most others).
For example: <code>
_ = chr log sqrt exp hex be = chr oct hex ord uc yz
</code>
<P>From these encodings, I especially like those relying on
that oct stops scanning a number when it meets a digit 9.
<P>What I find really strange is that expressions with <code>length aaaaaaaaaaaaaa</code> or those with <code>length qr taaaaaat</code> never give an optimal encoding.
