in thread Perl 6, defining a hash with interpolated string

Yes that is correct.

my $name='Larry'; my $pair = :$name; say $pair.perl;
Outputs:
"name" => "Larry"


UPDATE:
This is especially useful for named parameters in subroutine declarations.

For example:
use v6; foo( B => 'there',A => 'howdy'); sub foo(Str :$A, Str :$B){ say "Named parameter A is '$A'"; say "Named parameter B is '$B'"; }

    Thanks, that clears a lot up!


      Or to be even more concise, use the notation you showed earlier:
      use v6; foo( :B<there>, :A<howdy> ); sub foo(Str :$A, Str :$B){ say "Named parameter A is '$A'"; say "Named parameter B is '$B'"; }
