If you are importing, you'll need to change hyphens to underscores
user=> (ns sad-hyphen)
nil
sad-hyphen=> (defrecord MyRecord [a b c])
sad_hyphen.MyRecord
sad-hyphen=> (ns foo)
nil
foo=> (import '(sad-hyphen MyRecord))
ClassNotFoundException sad-hyphen.MyRecord ...
foo=> (import '(sad_hyphen MyRecord))
sad_hyphen.MyRecord
However, there is not generally a need to import a record, just use the ->MyRecord
and map->MyRecord
constructors (brought into your namespace via require/refer).
