Incompatible with clojurescript

[matdurand]

Hi,

Using version 1.0.6, the macro doesn't work with clojurescript. It works using version 1.0.5, so I guess the change in issue #9 made this incompatible. From what I know, alter-meta! doesn't work in clojurescript, so you probably need to use the reader conditional (https://clojure.org/guides/reader_conditionals) to make the alter-meta only applicable for clojure and not clojurescript.

Anyway, cool library! Thanks
