Yeah, right. $FruitStand.apples is not a direct access to the attribute,
but a method invocation (a call to a method implicitly created by Raku), so
it doesn't get interpolated within the string. So it should be outside the
string or used with a code interpolation block.
For example:
say "Fruitstand in {$FruitStand.location} has {$FruitStand.apples} apples.";
or
say "Fruitstand in ", $FruitStand.location, "has ", $FruitStand.apples, "
apples.";
or the construct with the ~ concatenation operator that you used.
Cheers,
Laurent..
