I'd use nil as the marker for uninitialized. This happens to be the
default and saves the overhead of all the empty strings. You can deal
with those nils later, i.e. when changing or outputting them, e.g.
def modify_whatever(s)
(@whatever ||= "") << s
end
def print_whatever
print @whatever || ""
end
You can even automate this by writing your own attr_accessor method that
will define getters like
def foo
@foo || ""
end

Form, what form?

Can you be more specific about what you are really trying to do? Is
this web, UI or what?
Kind regards
