anonymous function in state definition - 2.0.0-RC2

[toth-istvan-zoltan]

In 2.0.0-RC2 anonymous functions in the state definition generate an error.

• If I move the settings part out of server it works.
• Also worked in 1.9.10.

Branch to reproduce: https://github.com/spxbhuhb/adaptive/tree/anonymous-function-in-state-definition

The

        val adapter = server {

            settings {
                inline(
                    "EMAIL_HOST" to "localhost",
                    "EMAIL_PORT" to 2500,
                    "EMAIL_USERNAME" to "noreply@simplexion.hu",
                    "EMAIL_PASSWORD" to "helloworld",
                    "EMAIL_PROTOCOL" to "smtp",
                    "EMAIL_TLS" to false,
                    "EMAIL_AUTH" to true,
                    "EMAIL_RETRY_INTERVAL" to 5,
                    "EMAIL_RETRY_CHECK_INTERVAL" to 5000,
                    "EMAIL_LIVE" to false,
                    "EMAIL_DEBUG" to false,
                    "TEST_EMAIL" to "noreply@simplexion.hu"
                )
            }
       }
