[GSoC] unimplemented TS entries

[Fan You]

Hello,

My name is Fan You. I am a ETC master student from CMU.

I have 3 ideas regarding gsoc 2015:

a) I found 4 unimplemented Technical Specifications at
<https://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html>

- C++ Dynamic Array
- Invocation type traits, but dropping function_call_operator
- Polymorphic memory resources
- Extending shared_ptr to support arrays

I'd like to work on C++ Dynamic Array first, then finish others if I
have enough time.

b) After searching the mailing list I found 2 extra ideas:
- rewrite regex <https://gcc.gnu.org/ml/libstdc++/2015-02/msg00056.html>
- Rb tree node recycling patch
<https://gcc.gnu.org/ml/libstdc++/2015-02/msg00056.html>

Do you actually need people to finish those?

Regards,
Fan
