?public String getFrom$email_service() - d
dumptruckman
02/08/2019, 4:08 PMwhy not just getFrom? - d
dumptruckman
02/08/2019, 4:08 PMah, guess it’s something to do with internal? email-service is the module name - d
dumptruckman

dumptruckman

Shawn
02/08/2019, 4:14 PMbased on how modules are defined (https://kotlinlang.org/docs/reference/visibility-modifiers.html#modules) calling it from Java is (maybe) technically out of scope as well - d

03/20/2019, 3:09 PMHI! I was playing around with covariance in Kotlin and I wondered if it was possible to use covariance for Lists of subtypes that share the same supertype. - v

03/20/2019, 4:44 PMHi all, I'm using
on one of my collections and I noticed it maps to Map<K,V>, in my case the keys are always Ints, but I can't callgroupBy
because the function expectstoSortedMap()
which is the case in my usage, but I can't call the extension function<K : Comparable<K>> - v
