Groovy Removing Quotes in String Parameters

Question

I am trying to implement a simple DSL for scheduling events. I will have to put "schedule meeting" without quotes in a closure, and it should schedule a meeting. "schedule appointment" will schedule an appointment, etc. However, I cannot get rid of the quotes in my closure, as it registers 'meeting' as a property, and gives me groovy.lang.MissingPropertyException: No such property: meeting for class: groovy.SchedulerTest.

I know we can mark the function with "infix" in Kotlin, but not exactly sure how I could simulate that in Groovy.

Here is the class for DSL:

class Scheduler {
  //var meeting = "meeting" //I could uncomment this and it would work, but then I would need to create a new variable for every type of meeting
  String type

  def static create(closure) {
    Scheduler scheduler = new Scheduler()
    closure.delegate = scheduler
    closure()
    return scheduler.print_values()
  }

  def schedule(String type) {
    this.type = type
  }
  
  def print_values() {
    return "${this.type} scheduled"
  }
}

Here is the test case I am trying to pass:

class SchedulerTest extends Specification {

  def "Scheduler Type Test"() {
    setup:
    String type_test = Scheduler.create {
      schedule meeting //it runs just fine if I write -> schedule "meeting". But I am not allowed to use any quotes as my requirements.
    }

    expect:
      type_test == "meeting scheduled"
  }

}

Your test would pass if you added the following method to the Scheduler class:

def propertyMissing(String propertyName) {
    propertyName
}
