When making a UI there are a lot of binding/trace operations that need

don't really see lambda use like below.
Lambdas are very common in GUI callbacks but I admit I've never seen
tuples used to create multiple expressions. That's a neat trick I
hadn't thought of and will probably use.
I often uses as a debugging hack. Given:
foo=lambda: expr
I'll often write:
foo=lambda: (X("foo happening here!"), ...maybe more..., expr)[-1]
to embed some debug tracing in a lambda defined expression.
