I believe when we talk about lambda here, we don't exactly mean addressable anonymous functions :-)
# python lambda g = lambda x: x*x g(8) # 64 // JS lambda function lambda(exp) { var body = exp.split(":"); return Function(body[0], "return " + body.slice(1).join(":")); } var g = lambda("x: x*x"); g(8); // 64 g.name; // anonymous Regards On Wed, Jan 11, 2012 at 7:29 PM, Allen Wirfs-Brock <al...@wirfs-brock.com>wrote: > > On Jan 11, 2012, at 10:10 AM, John J Barton wrote: > > The blog post http://yehudakatz.com/2012/01/10/javascript-needs-blocks/ makes > the case for blocks that act like functions when passed as arguments but > have loop-up rules more like nested blocks. > > Of course these are called 'block lambdas', and I suggest that this is a > problem.
