All, the _ name is also used frequently in C++ for template-based lambdas. At least it is in many of the Boost libraries.

Eric, I believe that something like that, in C++ at least, is referred to as the curiously recurring template pattern.

No doubt it is extremely tough to think compositionally, and it's all too easy to fall back on non-compositional ways of thinking. In a similar vein it's all too easy to fall into procedural patterns when learning or working with functional programming in a multi-paradigm language. But what are good ways for programmers to learn to think compositionally and, more importantly, practice? Do you know of any books or online references that might help make the transition for anyone who is interested?

[Lift] Re: Wolfram Alpha integration for Lift
I haven't played much with WolframAlpha, but I get the impression that it
does better with quantitative results. For instance, if you were inclined
to compare the number of people in Chicago to the number of people in Alaska
you might create a query like this:
http://www33.wolframalpha.com/input/?i=population+of+chicago+%2F+population+of+alaska

Im not sure that drawing comparisons to google is right? IMO, they
dont do the same job...? I see why one would see similarities, but
isnt google's purpose to find the sources of information, where as
wolfram's aim is to provide an objective set of answers based on

Hey Ty,
Essentially the wolfram API is a REST / XMLRPC hybrid, so my plan is
to model a scala abstraction around Apache HTTP (similar to the paypal
integration) - speaking of which, i might actually abstract some of
the common factories out of lift-paypal into lift-util if applicable.
The interesting challenge will be that with wolfram, it can return a
whole bunch of things, they could be graphs, text, sound - so i'll
need some abstract way of making that presentable - perhaps some
decoupled thing with a core communication group, then some lift
specific abstractions for hooking into bind() or something...
I've not figured it out yet in my head, so any thoughts are most
welcome.
Cheers, Tim
