Without that, algorithms can't make
guarantees about their complexity, and it could have very
negative impact on
the performance of some programs.
Yeah. For the programs where efficiency matters but that are
never ever profiled.
Hi there,
I'm looking to write a function template that operates only on

As araq points out this should be caught in profiling.
Avoiding generality is not the best approach. A linear scan of a
SIMD friendly array that is in cache

You're not really supposed to worry about that. It's how dub manages the

Hello,
I would like to create a D function that returns a slice of a
string.
This slice shall be a reference to a part of the string argument.
Is this generally possible in D?
This is the function:

end) {
long a =

Thanks for your help
To do this you don't need to return a

You need to take a slice of the buffer:
char[] buf = Input[];
readln(buf);
// line now in buf
The reason for this is because you need to know where the string
ends. If you just passed in Input, how would you know how long
the line read was?

Quick question, how do I get pointer to a class constructor, let's say

You can access constructors just like any other method if you use
the __ctor name.
So like MyClass.__ctor.
