  Hmmm ...

multi sub chrs( Int *...@grid  --> List of Char )
C<chrs> takes zero or more integer grapheme ids and returns the
corresponding characters as a string.

  Is a C<List of Char> a "string" now?

  If the return value always C<does Str>, the return type should reflect
that, no?  (I assume C<List of Char> on its own does not; a dangerous

  OTOH, if it is not the case that this "string" necessarily C<does Str>, it
seems an interesting distinction to make – one that could stand to be
expounded upon? :)
