Comment:

 -[NSDictionary dictionaryWithObjectsAndKeys:] is a tricky variadic method
 (it accepts a variable number of arguments). There is no way MacRuby can
 know if a given method is variadic by asking the runtime.

 However, MacRuby can handle these methods if you load the appropriate
 framework metadata first.

 {{{
 $ macruby -e 'framework "Foundation"; p
 NSDictionary.dictionaryWithObjectsAndKeys("a","b",nil)'
 {"b"=>"a"}
 }}}
