[Richard Suchenwirth] 2005-04-08 - What happens when a [proc] calls itself. Popular in [functional programming]. In Tcl, we're a bit handicapped by the [[interp recursionlimit]] which is at ~380 on [Windows], even if set higher.

Here's an example for a recursive [integer range generator], so that [[iota1 5]] == {1 2 3 4 5} :
 proc iota1 n {expr {$n == 1? 1: [concat [iota1 [- $n 1]] $n]}}

[rdt] For completeness, shouldn't your definition of - (from http://wiki.tcl.tk/11389) be here also?
