Was talking to folks over on the #perl6 IRC channel.
It appears the recommended way is:
sub matching_chars(Str $chars_to_match, Str $str) {
# warnings, treats as string not variable
$str ~~ /<$_>/ given "<[$chars_to_match]>";
}

Sorry Paul, I don't get the correct answer in any of the three cases I
tried. Here's what 6Pad returns:
https://perl6.github.io/6pad/
sub matching_chars(Str $chars_to_match, Str $str) {
# warnings, treats as string not variable
$str ~~ /<$_>/ given "<[$chars_to_match]>";
}
say matching_c
I don't know then.
I've created the following ticket:
https://github.com/perl6/doc/issues/2999
Feel free to place your own input there if you feel the need.

I see. And that's discussed here (had to really look for it):

At first I was looking further down in the "Regex interpolation"
section,
