There are, actually, some more issues on using FieldStorage, for
example, you cannot ask for non-existing field:
v = form["nofield"].value
will raise KeyError. And there is no way to emulate dict.get()...
Oh, yes, I think I know why there is .value! What if your form has more
than one value for some key? Like in the following GET:
How do you get the value? How do you recognize thera are many values?
Currently, you try to ask for form["city"], if the field exists you try to
ask it for .value, but if the .value does not exists, you know it is a
for f in form["city"]:

Programmers don't die, they just GOSUB without RETURN.
