How does the Enumeration.Value of a scala enumeration knows the name of the member? -

-

in scala, can create enumeration this:

object weekday extends enumeration {   val monday, tuesday = value }

you can call tostring() name of member @ runtime 

val name = weekday.monday.tostring // name = "monday"

how possible? value method creates new object time, how can method access name of declared member without of compiler? pure scala magic me.
