i have another question:
when I do the following:
for(var prop in instancOfB){
//gets here only once as if instancOfB has only one member
}
bur if I do the following:
for each(var prop in instancOfB){
//will show the values of all props
}
the problem is that for each will not give me the prop name but only
the value. a simple "for" gives me a name and value but fails to show
all props.
