Re: How Powerful Is Parrot? (A Few More Questions)

Thanks to everyone for their information on Parrot. A couple more questions have come to mind. 1) Does Parrot support multiple inheritance? 2) Does Parrot support stack variables or is everything allocated on the heap? Thanks again. Dave

Re: CPP Namespace pollution

I don't have a specific proposal at the moment, but would invite others to think creatively about ways to minimize cpp pollution while still keeping the source readable and maintainable. One possibility would be to change code like this #define XYZ 123 to this... namespace _PARROT

Re: CPP Namespace pollution

This requires the use of C++, rather than C. See the FAQ. Where would the FAQ be? Dave Simon Cozens

Re: How Powerful Is Parrot? (A Few More Questions)

From what I've seen, supporting both garbage collection and true stack variables is a difficult task. Why is that? Because stack variables can refer to heap variables and heap variables can refer to stack variables. The garbage collector needs to be smart enough to handle all cases

Re: How Powerful Is Parrot? (A Few More Questions)

Thanks for the nice example, except I understand the issue you are speaking of, I was basically asking what parts of it do you think are more difficult to implement than any other major construct? I believe the main difficulty comes from heading into uncharted waters. For example, once

Re: How Powerful Is Parrot? (A Few More Questions)

Parrot supports deterministic destruction at the language level. If your language wants 'o' to be destroyed at the exit from f2(), then 'o' will be destroyed in whatever manner MyClass destruction means to your language. Resources allocated strictly by the internal representation

RE: How Powerful Is Parrot? (A Few More Questions)

That is exactly the case for C++. In your above code f1(), the C++ compiler already (behind the scene) inserts finally block for o destructor. That is why the destructor of stack allocated objects is called even when exception happens. The only difference is that the memory deallocation is

Re: How Powerful Is Parrot? (A Few More Questions)

In neither case do you have any control over the order that memory is compacted, or dead objects with destructors have their destructors called. If you must force some sort of order you need to do so within the objects destructor. Alternately if your program knows what order objects should

How Powerful Is Parrot?

I've been watching the Parrot development with interest and have a few questions about Parrots capabilities. Will Parrot support templates (also known as generics)? Will Parrot support operator overloading? Do Parrot classes have constructors and destructors? Does Parrot have garbage

RE: How Powerful Is Parrot?

Thanks Brent. # #Does Parrot have garbage collection? # Not yet, but it will. When it does, I'd ask that there be some sort of option on what type of garbage collection is used. This is because different methods of garbage collection have very different characteristics. For example,
