Using closures in a declarative step skips the step without any message.

I would expect the closures to work, but at least an error would be nice.

Steps to reproduce

1. Create Pipeline project
2. Paste pipeline script

   def wrapme = {String s -> "-- ${s} --"}
   def wrappedString = "${ -> wrapme('as var')}"
   def plainString = "string"
   
   pipeline {
       agent any
       stages {
           stage('Demo') {
               steps {
                   // This works
                   echo wrapme('explicit')
                   // This is skipped
                   echo "Closure: ${ -> wrapme('implicit')}"
                   // so is this
                   echo wrappedString
                   // and this
                   echo "String: ${ -> plainString}"
                   // And this line at least gives an error
                   //echo "As string: ${wrappedString}"
               }
           }
       }
   }
   

1. Build
   The output is

   [Pipeline] {
   [Pipeline] stage
   [Pipeline] { (Demo)
   [Pipeline] echo
   -- explicit --
   [Pipeline] }
   [Pipeline] // stage
   [Pipeline] }
   [Pipeline] // node
   [Pipeline] End of Pipeline
