currently:

cgi["field"] == cgi.params["field"]         # <= these return an array
string = cgi["field"][0]                    # <= array may be empty,
                                                 thus [0] may be nil
                                                 and must be tested

future:

cgi["field"] == cgi.params["field"].join    # <= returns a string
cgi["field"].empty?                         # <= true if "field"
                                                 is missing or empty.

Most of (my) time with web applications, I don't care about testing if
a field is missing.  I do care about testing to make sure it's value
is something sensible.  Thus, I don't miss the distinction of whether
a field is missing or empty.
