Documentation for method pairup
Documentation for method pairup, assembled from the following types:
method pairup(--> Seq) is nodal
Interprets the invocant as a list, and constructs a list of pairs from it, in the same way that assignment to a Hash does. That is, it takes two consecutive elements and constructs a pair from them, unless the item in the key position already is a pair (in which case the pair is passed is passed through, and the next list item, if any, is considered to be a key again).
say (a => 1, 'b', 'c').pairup.perl; # OUTPUT: «(:a(1), :b("c")).Seq␤»
