Temporaries can be passed by const reference - when the function returns the temporaries(Foo());
This compiles, but the problem is that now 'ref' is a dangling reference, because sequence here is:

I just hit a huge brick wall with Paypal. I had created a regular C# project to create some wrapper classes using their WSDL.
If you create a non-web project, the only option you get to add a wsdl is a Web Service Reference. And this builds kinda the ...

Adding a service reference allows you to create a WCF client, which can be used to talk to a regular web service provided you use the appropriate binding.

Is there any way to get Perl to convert the stringified version e.g (ARRAY(0x8152c28)) of an array reference to the actual array reference?
For example
perl -e 'use Data::Dumper; $a = [1,2,3];$b = $a; $a = $a.""; warn Dumper (Then some magic happens);...

Hello. I'm learning C++ and I'm still confused about this. What are the implications of return a value as constant, reference and constant reference in C++ ? For example:
const int exampleOne(); int& exampleTwo(); const int& exampleThree();

The const is here in order to avoid a new copy of your object .
Never thought, that we can return a const value by reference and i don't see the value in doing so is done when you pass an argument by value and not by reference).

I've found that I can import a SOAP/WSDL service that I plan on using into my solution either as a "Web Service Reference" (System.Web.Services) or as a "Service Reference" (System.ServiceModel / WCF).
I was wondering if what the differences were. I understand...

This generally will want to use the web service reference instead (since Mono doesn't support WCF yet.)
The preferred and most useful way is indeed....
With the service reference, your application will require the WCF layer to communicate.

In PHP, reference variables modify both when 1 or the other is changed.
New classes are formed by implicit references, but modifying the extension does not modify the parent.
Is this by PHP's design, or are they different kinds of "references?"

By reference is a completely different conversation and isn't really connected to the idea of subclassing; $childRef = $child; // $childRef isn't a copy, it's a reference to $child.

Java/C# language lawyers like to say that their language passes references by value. This would mean that a "reference" is an object-pointer which is copied when calling a function.
Meanwhile, in C++ (and also in a more dynamic form in Perl and PHP) a...
