proc is already a delegate, so is a pointer to the delegate,
just pass a `proc` itself
Thanks done that but getting a range violation on z which was not there
before.

I don't know a better way, I think you enlist all possible ways - get a
value using either `front` or special range member. I prefer the second
variant, I don't think it is less consistent with range

Sorry for offtopic, imho both Qt and Gtk are too complex in case of
virtual list/tree view. I think the reason is they are retained mode
gui. I gave up to use them for that and develop custom virtual tree view
that is easy in use and currently capable

Hi,
I need to start a process before the tests run, and terminate it after

There are also other switches like -boundscheck and -check. It’s

Before I lived in assurance that asserts are actual only in debug mode
and in release mode they are nothing (except `assert(0)`). But today my
whole life is going sour because I stumbled upon assert in release mode
and of course that assert is failing.
