Subject: Re: a most undangerous Hash#store!

Trans [mailto:transfire@gmail.com] :

#   # As with #store but adds the key/value pair
#   # only if the key isn't already in the hash.

just a suggestion: *not another new method name (since we're still updating/merging, right?). just add an option  --if possible ie

merge :nodup
update :nodup

merge require => :nodup
update require => :nodup

merge :safe
update :safe

merge require => :safe
update require => :safe
