Title: dup function request

Lutz,

I know you've been working away here lately but, I wonder if you could add a (dup function. In almost every program I write, I duplicate something: a string, list, symbol, number, etc. An example of a function is:

(dup "ab" 0) => ""

(dup "ab" 3) => "ababab"

(dup '(1 2 3) 0) => ()

(dup '(1 2 3) 3) => ((1 2 3) (1 2 3) (1 2 3))

(dup 4 0) => ()

(dup 4 3) => (4 4 4)

(dup ab 0) => ()

(dup ab 3) => (ab ab ab)

Would anyone else like to see this added? Would you like to call it something else?

Eddie

For the string repeat we had some discussion here:

A generic dup sounds usefull to me.
