I'm not familiar with piece, but it occurred to me it might be useful to
get attributes groups in some way. My first (passing) thought was to do...
host, port = host.partition(':').(head, sep)
Where that would be short calling a method to return them:
host, port = host.partition(':').getattribs('head','sep')
But with only three items, the '_' is in the category of "Looks kind of
strange, but I can get used to it because it works well.".
