Neat. Neater, see below. ;-) *** Trigger Warning *** Raku content *** Trigger Warning *** Notes: The ! after $dbh, in the signature of the TWEAK method makes $dbh argument required. The colon indicates it is a named argument, rather than a positional one. Attributes are always read only by default. The |%$dbh does two things. The % "dereferences" (rather re-containerizes) the Hash in $dbh. The | then flattens that hash into named subroutine arguments. holli You can lead your users to water, but alas, you cannot drown them.
