Complete newfag here

Hai, I'm a newfag to C++ and to this board so excuse my giant amount of fail.
Why won't this figure out the smallest thing in the array?

Oh, yes, I wrote that by hand, so I didn't notice, it produces (1 1.5 ... 4.5 5).

I wish Scheme had constant? too. It's not so difficult to implement, but it's boring and uninteresting.

Again, Scheme/Racket hasn't compiler macros, so if you have to optimise something (like, in this case, generating a list at compile-time), you have to write a macro.

I'm about to start learning CL, what compiler do you suggest me? Is SBCL a good choice (on Linux)?
