Re: [std-proposals] Fwd: set_new_handler extension

- Ok so at that level 90% of the low-level race-conditions are already solved;
- The container::empty() could return a temporary object that can be converted to a boolean but also locks the internal recursive mutex;

I assume here the temporary object will last for the duration of the condition but I will double-check that later. If not then the rules can always be extended.

If that still doesn't work for some reason then I'll just automate it with C++ Superset. Very simple.

If the programmer can't write proper high-level algorithms then that's
another story.

But if the programmer can write high-level algorithms, the low-level silent
locking you're proposing is, at best, overhead. At worst, it's counter-
productive causing deadlocks that the programmer needs to workaround.

As a quick example: how would you write the code for "if the list is empty,
append value 1" (remember: multiple threads will be running this code).
