And String.length as well. This is done for JVM interoperability: java.lang.CharSequence is an open class and has a function 'length()' which should be implemented in subclasses somehow. A minor unexpected effect of this is that String.length() is now a compile-time constant (it wasn't such as a property because properties are not supported in compile-time constant evaluation) #KT-3571 Fixed
