Two natural candidates which come into my mind would be an unary '&' and 
the '%'-sign:

  '%' (percent) indicates some kind of conversion anyway (though usually 
      in postfix notation, not as a prefix, "75 %" for 75/100). 

  '&' is something you can even now use for conversion into strings and 
      the like:
        declare an appropriate function 
            function "&" (X: String; Y: Some_Type) return String;
        and then just write 
	    "" & A;
        wherever you need A being converted into a string. 
      A unary "&" would be handy -- prepending the empty string clearly is

      artificial. 

So long
