Thanks for the question; I learned something too. :)
But in case you don't already know, there is also the D.learn newsgroup.
This question might be more useful there.

Say I'm doing that enum a = calcPrimes();

auto, enum, immutable, and const all use type inference. So, you can declare

pure != CTFE
If a function is pure, then it's result can be cached if it's called again with
the same arguments. So, if you hade a pure sqrt() in an expression like so
auto x = sqrt(2)
can the enum be a float? if calcprimes returned a float? - and if so, will
the enum be a float or an int? (will it be casted, or will it work as an
auto type?)
thanks btw :)

Yes, effectively you are declaring an anonymous enum with one element.
By default an int.
ah ofc! I shoulda know :) - So I were doing it wrong :)
Say I'm doing that enum a = calcPrimes();
then a will be an enum with 1 element, that I can use as an int right?
- or is there something special to be aware of?

Immutable means that the variable, or the memory it points to, will
not change. You can still assign run-time values to it:
void main(string[] args)
{
immutable string a = args[0];

Make your result an "enum" (i.e. compile-time constant) if you really want
to calculate it in compile-time:
enum primes = calcPrimes();
So I wrote a program, to find prime numbers, just to check out this pure
thing;
http://gist.github.com/608493
However, the program has a runtime of about 5 seconds? - in my mind, if the
function is pure, shouldn't the compiler insure that it was evaluated at
compiletime? - or am I doing it
