Yes indeed, that seems to be all it is. Thanks much.
And maybe I'll go back to monster names in my demos.

You overlooked a mistype. The subset expects "wuhn", you pass "whun" instead.
Guess, the subset is wrong about it. :)

Different behavior for strings and strings in variables with multi-dispatch using a subset
In this code I'm using multi-dispatch with a subset type that
makes string values special: "wuhn", "tew" and "thuree".
use Test;
multi sub whats_my_type (Str $item) {
return "This is a Str: $item";
}
subset GoofyNum of Str where { $_ eq any( 'wuhn', 'tew', 'thuree' ) };
multi sub whats_my_type (GoofyNum $item) {
return "This is a GoofyNum string: $item";
}
{
my ($ret, $arg);
$ret = whats_my_type('two');
like $ret, /<< Str >>/, "quoted string argument of 'two' is Str";
$ret = whats_my_type('tew');
like $ret, /<< GoofyNum >>/, "quoted string argument of
'wuhn' is 'goofy'";
$arg = "one";
$ret = whats_my_type( $arg );
like $ret, /<< Str >>/, "string in var argument of '$arg' is Str";
$arg = "whun";
$ret = whats_my_type( $arg );
like $ret, /<< GoofyNum >>/, "string in var argument of 'wuhn'
is 'goofy'";
}
I would think all four of these tests should pass, instead I see
the last one failing: for some reason there's a difference in the
case of a simple quoted string, and a string inside a variable.
Any comments?

Rakudo-Star 2021.09 (Windows MSI and Linux RSTAR) packages
Hi all. Who ever is interested in a Rakudo-Star "latest" Windows MSI or Linux RSTAR package... you may want to get 2021.09 from here [1]. Please be aware that the Linux RSTAR package changed a bit compared to its "origin" in [4] The previous Windows MSI build under [3] is also updated to 2021.09... just in case someone was using this repo and it's versions somewhere. Midterm I plan to "discontinue" [3] and send pulls to merge [1] into [4] @RakudoDevs: feel free to comment on the changes I made in [1] @Patrick, feel free to copy packages from [1] to [2] again... Regards AntonOks [1]: https://github.com/AntonOks/star/releases/latest [2]: https://rakudo.org/latest/star/win [3]: https://github.com/AntonOks/rakudo-star-win/releases [4]: https://github.com/rakudo/star
