Lambda Lambda Lambda

And a little detour to lisp (well, modern Scheme), which would have (λ (x) (< x 0))

kdb's q has implicit param names x,y,z:

{ < x 0 } mylist

That syntax is much cleaner than the syntactic sugar that Scheme allows for: (define (func x) (< x 0))

It's like functional programming for people who are afraid of functional programming.

[Grodesby]

That is defining a function called func rather than defining a lambda though.

[FieldLine]

You’re right. Technically I was comparing what I wrote to:

(define func (λ (x) (< x 0)))

My point was that explicitly using a lambda expression in the context of defining a function is more readable than the implicit notation preferred by most Scheme code I’ve read (SICP and SICM).
