I have just found the description of the construct you refer to in S12, and I like it pretty much. For those monks, who, just like me, quickly get tired of the overdose of Perl 6 that comes with a Synopsis, I copy the relevant part here verbatim:

Parallel dispatch

Any of the method call forms may be turned into a hyperoperator by treating the method call as a postfix:

    @object».meth(@args)   # calls one method on each
    @object».?meth(@args)  # calls method if there is one on each
    @object».*meth(@args)  # calls all methods (0 or more) on each
    @object».+meth(@args)  # calls all methods (1 or more) on each
    @object».=meth(@args)  # calls mutator method on each
    @object».:meth(@args)  # calls private method on each

Pretty nice, I think. Is there any other programming language that allows anything similar to Perl 6 parallel dispatch?
