For the sake of accuracy: While this calls itself an interpreter, it actually isn't. It's a compiler generating threaded code for immediate execution upon call. It's sort-of similar to the Thompson-shell because it relies on separate programs for providing any 'real' functionality, including 'control constructs'. _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
