Re: Using Do Code Method to make static method calls: safe practice?

Andreas,

There are those that would ague that Singleton Patterns are inherently evil as they effectively push the scope of the instance into the global namespace. I don’t believe that to be universally true and there are certainly times when a Singleton is an appropriate solution. For that reason I too would like to see support for a private $construct and while we’re at it, true static methods.
