It really is call by name. In your case, the name is "RAND()" The name in question is an expression (well, a closure) rather than it's value or a location containing its value.

If you printed it three times in a loop it would be the same all three times. With call-by-name, 'RAND()' (or whatever) would not get evaluated by the caller but rather passed to your subroutine "as-is." It would get evaluated whenever your subroutine referenced it. If you printed it three times in a loop you would get three different values. It's not really "call by name" but rather "call with function" as opposed to "call with value of function." Charles
