Ben, my imagination is probably too weak, but what is the usecase of an
unconditional breakpoint that you have in mind?

Looking at my usecases in the recent past, I can see two additional
variations:

1) something like 'break_if(expression)'
Like the proposed std::breakpoint but with an 'expression' that's
convertible to 'bool' as an additional condition that's evaluated only
when 'is_debugger_present()' evaluates to 'true'.

2) something like 'wait_and_break()'
Wait until a debugger attaches and then break into it. An overload might
take a chrono::duration to limit the wait portion.

I've been using both in situations when the standard, built-in debugger
features just didn't cut the mustard.

Ciao
