Well, I'm afraid that despite devoting all my time to Loyc recently, I remain several years behind schedule. It is probable that I will write a Loyc tree library for Python before I get around to doing something involving tree-hugger + .NET. A couple of days ago I sketched out something called BLES, which is a syntax for Loyc trees designed as an extension of JSON (and subset of LES2). In these grammar diagrams, the things BLES has in common with JSON are shown in black, while changes are shown in blue. It looks about twice as complex as JSON, but probably about one-quarter as complex as C. So this is something I could port to other languages more quickly than other versions of LES. There's also a JSON encoding of Loyc trees but I'm not sure if that's useful to anyone.
