but if I dont want to force @list in scalar context ???
since ~> and friends are _pure_ grammar while given is not ,
probably we can have unary postfix ~> ( or |~> )
{
@list ~> ; # ( or @list |~> ; )
~> grep length == 1 ~> @onecharthings;
~> grep [0..29] ~> @numberslessthan30;
~> grep /^\w+$/ ~> @words;

}
as a way to multiplex @list
