Subject: Re: type specific operator

Thanks for making me correct. But as in case of x + y it gets converted 
to x.+(y). So here the type of x must be known(that is what I mean by 
checking type of x) and also to execute + method of x's class and to 
pass it argument y, type of y must be known(that is what I mean by 
checking the type of y).
These checkings will be done at run time. My question is if we have an 
Idea about the type of x and y initially(at the time of writing the 
program) can we eliminate these type checks. I mean is there any 
operator or method call that will directly treat x and y as fixnum. i.e. 
something like
                       int+(x,y)    //specific function for adding two 
integer
                       string+(x,y) //specific function for appending 
two strings
or any thing like that which will directly treat x and y as variables 
known types

I hope you will be getting my point.
Please give me the details if there is any such thing in ruby.

Thanks
amitraj
