Not following naming convention breaks compileKotlin

[aafanasev]

data class NamingTestImpl(
    @Secret val UpperCaseName: String,
    @Secret override val UpperCaseNameInterface: String,
    @Secret val snake_case: String,
    @Secret override val snake_caseInterface: String,
    @Secret val justBoolean: Boolean,
    @Secret override val justBooleanInterface: Boolean,
    @Secret val hasBoolean: Boolean,
    @Secret override val hasBooleanInterface: Boolean,
    @Secret val isBoolean: Boolean,
    @Secret override val isBooleanInterface: Boolean,
    @Secret val booleanInterface: Boolean,
) : NamingTestInterface

interface NamingTestInterface {
    val UpperCaseNameInterface: String
    val snake_caseInterface: String
    val justBooleanInterface: Boolean
    val hasBooleanInterface: Boolean
    val isBooleanInterface: Boolean
}
