In the odd parallel universe where most perl 6 flow control is handled
by the throwing and catching of exceptions, the next/last/redo controls
are macros for throwing next/last/redo exceptions.  Loop control
structures catch these objects and throw them again
if they are labeled and the label does not match a label the loop control
structure recognizes as its own.
