fix order of directory/volume used in dir()
A temporary fix for faster module loading

*All* directories and *all* types were being checked, whereas always only the
first was being used.  This quick fix short-circuits search as soon as the
first candidate is found.
Fix for autoviv Typed hash problem

As suggested by jnthn.  I think there is a ticket for this, but do not know
its number.
Fix for "exists" handling on typed hashes

Made in cooperation with jnthn++ and moritz++
Make List.gist not warn on undefined values
.gist is better for defined values than .Str
add S02-names/bare-sigil.t to spectest
Fail on default constructor
empty constructor in DateTime class, not Date...
Added gist to DateTime
Always just use .gist to create the final .gist

As suggested by Moritz++
