|How about this?

Unless you really really seek compatibility, faking something behave
like both Array and String tends to cause trouble.  For 99.8% of the
cases, we get single value for a prarameter.  So how about making
cgi["key"] just return a string, and prepare advanced API (say,
CGI#params(key)) if one requires a multiple valued parameter.
