lambda

lambda see closures

The javascript closures notation x => x*x is beautiful but a bit hard to type square = x :: x*x // could confuse c++ folks etc

Are the concepts of map and closure unifyable? Ifs so one might simply write square = x : x*x todo LHS of ':' could be an expression, a symbol or a string square = "x" : "OK" adhoc map.

square x := x*x only makes sense for named functions
