Identity Dictionary - Is this possible?

@jamshark70, you coded this fab Class LambdaEnvir a few years ago:

Order of execution

Had a bit of time at lunch, so I POC’ed something. The “something” I was thinking of involves the difference between push and pull models of computation (which James McCartney mentioned in passing at the first SC symposium, years ago). Pbind and SynthDef building are currently “push” models – you start at the top and push values down. In this model, calculations have to be written in the right order – if B depends on A, you can’t do B if A happened to be written later. But an alternate model …

which allows one to write:

LambdaEnvir((
		a: 200,
		b: { ~a+2 }
)).b               //202
