$ ruby -r./cgi.rb -e'value = CGI.new["key"]; p value' key=value
"value"
$ ruby -r./cgi.rb -e'value, = CGI.new["key"]; p value' key=value
"value"

cgi['field'] is return String. but,

$ ruby -r./cgi.rb -e'value = CGI.new["key"][0]; p value' key=value
WARNING! cgi['key'] is return String. if want Array, use cgi['key'].params
"value"

$ ruby -r./cgi.rb -e'value = CGI.new["key"].first; p value' key=value
WARNING! cgi['key'] is return String. if want Array, use cgi['key'].params
"value"

How about this?

Of course, in the future, cgi['field'] is return pure String, and,
warning is disappear.
