Nice expression for the usage test. Maybe one can add function "dec2base", cause the return type is a String.
The problem description should mention that dec2base isn't allowed either.
This will fail to detect certain palindromes which contain zero e.g. 10101 however the test suite doesn't (yet) contain any such.
There's something strange with the Cody test suites today...
