I am moving some code to use spec and namespaced keywords under Clojure
1.10.0 (release). One group of keywords starts with a numeric character
after the colon, which has worked fine in the non-namespaced context.
Creating and using the namespaced keyword works correctly in the local
namespace (using only the double-colon), but fails with "Invalid Token"
when dereferencing from another workspace.
I'm not sure if this is a bug or if I have been taking advantage of an
undocumented/unsupported feature.
Having a leading-digit keyword has been very useful, as the names are an
exacting fit of the problem domain and don't suffer from the addition of
any visual pollution.
user=> (def example-a {:015-00 "015-00"})
#'user/example-a
user=> (def example-b {::015-00 "015-00"})
#'user/example-b
user=> (:015-00 example-a)
"015-00"
user=> (:015-00 example-b)
nil
user=> (::015-00 example-b)
"015-00"
user=> (::015-00 example-a)
nil
user=> (ns try)
nil
try=> (:015-00 user/example-a)
"015-00"
try=> (::user/015-00 user/example-b)
Syntax error reading source at (REPL:1:15).
Invalid token: ::user/015-00
Syntax error reading source at (REPL:1:31).
Unmatched delimiter: )
try=>
The current behavior is certainly inconsistent, even if it is not a serious
bug.
Thank you!
