a. Is there a *reason* that square brackets have to be used for
postfix function args in lambdas?
b. It seems like
lambda(X)[ let[ Y == X %plus% 3,
F == minus[2]
],
F[Y]
]
would be a little sweeter, syntactically speaking.

isn't there a parsing issue here? Where the "," impiles two arguments to the Lambda(X)[] function call, when you really want one fc++Lambda object from binding the "," first. which makes you write:
lambda(X)[ (
let[ Y == X %plus% 3,
F == minus[2]
],
F[Y]
)
]
which for me is worse. As the let has to generate an object that is unique enough to be recongnized to bind to the F[Y] and generate useful compiler errors otherwise.
Note: my opinion is really biased as Jaakko and I came up with a different syntax.
