I'm using [deraen/lein-less4j "0.6.1"]

I'm quite sure the problem is in Clojure, not here.

[Claire Alvis]

I am reasonably sure this macro falls under 2 here: https://groups.google.com/d/msg/clojure/_slHTn-Ej1Y/1dY0n_3uCQAJ

because replacing compile-less with ~'compile-less fixes the problem

[Juho Teperi]

Ah, right, now I understand even the spec error.

[Claire Alvis]

Yeah, the spec error is not the most helpful description, I don't see a check for a namespaced symbol. Had to go google searching.

Do you want to send a PR with the fix?
