[ tie->foreach ]
The [tie->foreach] method invokes a capture block on each element in the tie. The method requires a capture block to be passed to it. The capture block is invoked on each element of the tie in turn (i.e. the capture block is invoked with each element of the tie). The current value in the tie can be accessed using the #1 variable.
