Isn't the question about

check

in #getting-started channel of any interest for you?

I'd still have to catch the Exception from

check()

though?

check()

throws

IllegalStateException

exception

I was hoping to avoid exceptions completely... Something like

if(it.key in PostMetaData.values()) { val metaData = PostMetaData.valueOf(it.key) // happy meta data path ...} else { // some other code}

if (PostMetaData.values().none { it.name == key }) println("No match") else println ("Match found")

?

In the end I wrote a function on the enum - thanks for the suggestions though.
