Well I just mentioned the problems (security, efficiency, robustness,
..). Here are the solutions:

1) Well for the security part solved by C++ Superset, here's its

But C++ Superset is patented and commercial so I don't expected to make
it part of the standards but if some corporation would like to partner
up then we can discuss. I already talked to Intel but I put emphasis on
the incomplete Python -> C++ source-to-source compiler. C++ Superset
works perfectly well but parsing all types syntax of existing code,
without requiring modifications, is the part I slightly still need to
fine tune.

2) For low latency FIFO containers we can integrate the following one:

It is still incomplete as it lacks a simple subtraction for deallocated
blocks but you get the idea.

It is 3.6 times faster under Linux so I expect an even greater standard
deviation under Windows.

3) I know C++ hash maps are very slow and all companies requiring fast
hash maps replace the standard one. So some attention should be put there.

Even Linus Torvalds would stop complaining C++ is fixing the wrong
problems because he's definitely right.

Thank you,
