Description

user=> (keyword "")
:
user=> (prn-str *1)
":\n"
user=> (read-string *1)
java.lang.RuntimeException: java.lang.Exception: Invalid token: : (NO_SOURCE_FILE:0)

This obviously isn't a huge defect, but I'd argue that anything that can be printed should be readable.

Patch that throws IllegalArgumentException would be ok for this.

After a brief review of places that call intern, it appears that this problem might never be reached in the reader, only in user code calling (keyword ...). Does it make more sense to have the patch there, and a matching change for (symbol ...)?
