You can lend friends money. Just not money you would mind losing. It's like gambling basically.
Side note: I once loaned a small amount of money to an annoying "friend" who then apparently fell off the face of the earth. It was worth the money. Although I suppose I could have achieved the same effect by just being a d*ck about his sob story, but that eats at your conscience a little more.
Though I imagine the problem for larger computations could be that you're limited to writing functional-style code, at which point you might be better off using a language designed for it?
Point taken, assuming it has to be fast and there is that much critical code.
What optimizations does gcc actually do on pure functions, having identified them?
Well, it doesn't dispatch them
The first time I saw the "brain" scene
I was eating vermicelli at a Vietnamese restaurant, with a bunch of kids running around the tables, and Hannibal was playing (muted) on their big screen TV.

they have no mutable variables in the usual sense
I think the key word here is "might".
Nothing prevents a C compiler from figuring out "int foo(int a) { return a + 2; }" is pure. In fact gcc can do this to some extent; the relevant compiler flag (enabled by default w/optimization) is "-fipa-pure-const".
gcc also lets you specify the attribute 'const' to declare that a function is pure (in the sense that we're using it here).
Sure, it's coarse, and an afterthought, but it's also flexible.
Well, maybe both.
Yes I probably wouldn't enjoy being on a site that went on and on about "Windows Rocks/Linux Sucks" (as much as this site does the reverse, anyway).
But that kind of rhetoric is not really why I read this site. As an example, I found the (apparently) 1st-person accounts about air traffic and ATC procedures yesterday to be one of the most informative and entertaining bits I've read in awhile.
Slashdot has (more than?) its fair share of trolls, and troll articles, but there is (sometimes) a depth here that I haven't really found anywhere else yet; and that includes your local newspaper.
ClearCase also supported the typical 'check your workspace ("view"?) out to a local place on your hard drive, rebase it occasionally, make your changes, and check it in' model, and that seemed to work fine.
And yes we had a full-time administrator for the system. Would've been suicide not to.
I mean, the reward for waiting actually needs to be worth something.
And for my own personal use, I'd love to be able to throttle a dos 6.22 VM to 486 speeds so some of those ancient programs can be ran for historical purposes. (Without bombing the processor with dummy NOP and other MOSLO crap so we keep our power consumption down.)
I assume you've checked out DosBox and its 'cycles' configuration option/command? It's not precise but it works quite well for me.
