battling with a c++ example that refuses to compile. It's from Stroustrup's C++ book -- how can it not work?! 
Copied manually or cut and paste from online? If the former I bet there is some teeny tiny error in transcription.

you're either psychic or a programmer. 
Went out for a walk, came back and immediately saw the stupid typo.

Hehe - yep, been there, done that
Yup, when something I've coded just REFUSES TO RUN no matter what effort I put into it, I just push back and go do something else for a bit.
One script I wrote kept giving the same error no matter what I did. I slept on it and it ran perfect the next day, no changes. 
That one is probably more an example of magic...
Or sleep coding.

I hate it when it happens the other way round: yesterday it worked fine, today it fails.
