Could you please show a daily example of any *need* for
trampolines? I mean code, which could only be implemented
(efficiently) via trampolines.

I never saw one generated by GCC and never wrote an explicit one
by myself. So for what important piece of code we do need it and
can't code it without trampolines?

Thanks in advance
