I must ask once again how do we know it is "too much" overhead? Where is
the real-world program which would be impossible or difficult to write
otherwise?

For some reason I never get an actual answer, and instead it's always
something along the lines of "I'm an expert, trust me, I know". Well, I
don't. Sorry.

This applies to C++ exception handling and error handling in general. Yes,
I know, there is overhead -- but where is the proof that 1) it matters, and
2) it's not worth it?
