I want a module level initialised delegate. if I try
module foo;
enum Status
{
success,
}
class StatusException : Exception
{
Status s;
// usual exception constructors
}
void delegate(Status) onError = (Status s) { throw new
StatusException(s);};
I get a error like cannot initi
As far as I can tell, this code should compile:
class B { int a; }
class D1 : B { int b; }
class D2 : D1 { int c; }
template TupleOf(Classes...)
{
static if(Classes.length > 1)
alias TupleOf = AliasSeq!(Classes[0].tupleof,
TupleOf!(Classes[1..$]));
else static if(Classes

You may want to look into ndslice package source code [1] --Ilya

Thanks. I don't normally compile right into a .so, but I think
this is OK:

I would like to know that command line (I am on Linux) I would
use to compile a D file and create an object file that is
suitable for a Linux dynamic library (.so).
I believe it is probably

Also, what is the command line to create a dynamic library from

Have there been any investigations into using region-based memory

GC allocated memory? This would be a very speculative idea, but
it'd be interesting to know if there have been looks at this area.

Well the purpose of the exercise kind of *is* to write a prime
number generator. You can look up prime number sieves and
algorithms. For REALLY large numbers, that takes an insane
amount of time, and you can instead use algorithms such as the
ones outlined at

Hi,
Does Phobos have an isPrime function? I cannot find it in the
library. I currently have a look at projecteuler.net problem no
7. Such a function makes it a lot easier to solve the problem.

Kind regards

I am trying to have a multi-dimensional array and opIndex has to
have both an arbitrary number of parameters and allow for slicing.
The problem is if I create opIndex for non-slicing, it looks like
ref auto opIndex(T...)(T index)
and this one catches all templates. But slices do not return the

What's the correct way to check if a variable has been defined? (note x
may or may not be defined above. I need to know if it is)
Check to see that it has a type:
static if(is(typeof(x)))
{
}

It's called by multi-dimensional opIndex (or opSlice and perhaps
others?; can be very complicate
