Your right about the argument count. Here is a perhaps useful use for this
( useful use, an interesting phrase)

 def call_type_self(*y)
   caller[-2] =~/(\w*)'/
   send(y[0].type.to_s  + '_' + $1.to_s  ,*y)
 end

def polyfunc(x)
    call_type_self(x)
end

def String_polyfunc(x)
    #use string
end

def Fixnum_polyfunc(x)
    #use num
end

On the regex stuff.  I'm still learning too.
