Honestly, I don't know what you even mean by purity.

It's not a decision about whether or not to use generics, it's a decision about whether or not to make it possible to use generics. The developers have decided that they should make it possible for themselves to use generics, but imposs

If Reader users were dropping off because Google crippled Reader, then the "users were dropping off" argument lacks teeth, though it does make for a great self-serving justification. First you make the product worse, then you point out that

And yet of course you could have responded. You could in fact have simultaneously pointed out that you find the tone of the original post unfortunate and then also addressed the substantive issues raised therein. "I can't respond" is ludi

As a tangent, it's not really true that "a public company [has] a responsibility to generate return on capital". See, e.g., Stout's _The Shareholder Value Myth_, or this shorter thing: http://crookedtimber.org/2008/07/25/what-obligation-ma

Yeah. But you could decide how much of the stack to keep, at least. Nevertheless, I know that some smart persons (I just can't remember who!) have addressed this issue in a significantly subtler way---wish I could find the reference.

Off the top of my head I can think of a doubtless unsophisticated way to recover the "stack" in this situation: namely, the same way you recover the "stack" in the factorial example, by using an accumulator hidden in the interpreter. When f

That's bullshit, however, because: (a) there are techniques to deal with that, and (b) where's the accurate stack trace from a state-maintaining while loop, or a trampoline?

http://hackage.haskell.org/package/HList-0.2.3 sure seems like an "implementation" of heterogeneous lists.

Well, the Clojure repl is way better. Not being pervasively lazy makes it easier to reason about many things. Not strictly boxing IO in the IO monad makes it easier to debug (debug by println is still useful!). Macros are much easier to u

Oleg Kiselyov uses exceptions for control flow in his Delimcc library for Ocaml, and if that doesn't establish that doing so is perfectly acceptable, I don't know what could.

You are unlikely to see many books where this has happened, because professionals try to make sure that it doesn't, and fiddle with things if it does.

" To clarify, I was trying to use "specious" as a synonym of "flawed." I thought this was the common usage, but apparently not." "Specious" does mean, more or less, flawed. Zero benchmarks are better than flawed benchmarks.

Not currently, but it would certainly be possible to add something like that---exposing the running stats for partial subsequences of the input sequence would just be a matter of replacing the "reduce" in the definition of calculate with

Interesting that among the other languages he mentioned one did not find Fortran or ML, which, I believe, were the go-to examples of C-beating languages in the discussion of the initial piece.

Sure, and Clojure has '&' in function argument lists for rest arguments. Here's a Clojure example: user=> (for [x [0 1 2 3 4 5] :let [y (* x 3)] :when (even? y) z [1 2] [y z
