int main() {
    EventHdl handler;
    Channel serial_out(handler, uart_info);
    Button left(handler, serial_out, ...), right(handler, serial_out,
...), confirm(handler, serial_out, ...);

    handler.process();
}

instead of recoding the glue logic everytime I want a new device with
three analog inputs, a matrix keypad and an LCD screen. This takes me
1 minute to write and think up, including making all handling
asynchronous, polling-based or such. Writing that in C is a lot more
error prone and allows less abstraction, in particular having
functions that "belong" to a given struct are useful for keeping stuff
ordered.

I have a concept for dynamically distributing information on a
hardware system that I intend to test using this, but it's highly C++
specific and complex in implementation. When compiled for a leaf node,
though, it could be substantially reduced in size by its limitations,
but that would require C++ support or I'd have to recode everything in
a variant of C, keeping both code bases synchronized.

Using something like this plus a cheap kind of microcontroller would
allow me to add a new one to an existing design for nearly no expense
in terms of development time - you configure the device in a few
minutes, you compile & install the output application and don't think
about it anymore.

Thanks for the helpful replies, though.
