Well ... you certainly think you are funny ... ¹

Do you know if this approach involves changing the nature² of the scalar after its first use, to speed up things afterwards?

(Maybe I'm confusing this now with quantum superposition magic ...)

¹) you are! ;-)

²) i.e. unblessing

    I don’t know but I’d be very surprised if it did. This is not my forté, more my piano (see! I am funny), but this seems to support the notion; both dumps being the same– 

    use 5.012;
use Devel::Peek;

package Bingo {
    use Moo;
    use overload '""' => sub { +shift->ohai };
    has ohai =>
        is => "rw";
};

my $bingo = Bingo->new( ohai => "DER" );

Dump $bingo;
say "\n$bingo\n";
Dump $bingo;

      Sorry my question was not well phrased.

      Maybe better "involves possibility" or "allows".

      The point about a "want context" is to return the right data type.

      Returning an object could be a work around, if it transforms into the right data type after first access.

      Otherwise there would be a performance penalty for simple scalars.

      But not sure if unblessing or untying within an accessor is a reliable approach with calculated risk.

      Cheers Rolf
