URI::ws ended up on my list because I used list-modules and diff to find out which modules were missing to make my list that was posted here. Something is not right with perlbrew (I guess it's perlbrew but who knows)! Check this out:

% perlbrew use perl-5.38.2                    
% perlbrew list-modules | grep 'URI'
URI
URI::Find
URI::Find::Delimited
URI::ws

% perlbrew use perl-5.42.0                    
% perlbrew list-modules | grep 'URI'
URI
URI::Find
URI::Find::Delimited
