(transform-keys ->kebab-case-keyword data-map) failed for numerical keys

[sr3d]

for a map such as { 1 {:a "b"} }, calling transform-keys ->kebab-case-keyword would throw an exception since it tries to symbolize the numerical key.

ClassCastException java.lang.Long cannot be cast to clojure.lang.Named  clojure.core/name (core.clj:1587)

The desirable result is that numerical keys are kept in tact and only text keys are converted.

This also affects UUID keys.
