Part ... of the [Feather] extensions. lambda Creates a lambda command object. Apart from the lack of name the semantics of ... this command are the same as for a proc. e.g. ======none % set add [lambda {a b} {puts "([info level]) $a + $b = [expr {$a + $b}]"}] % $add 1 2 (1) 1 + 2 = 3 % set add2 [curry $add 2] % $add2 6 (1) 2 + 6 = 8 ====== ---- The Tcl 8.5 [apply] command provides similar functionality. <> Concept
