FWIW, when making my own async IO library in another language, I was inspired by 
error_code and made something similar. I quickly came to the same conclusion 
that the name did not accurately reflect the use, and renamed it op_result.

I also found the implicit bool conversion was very error prone, as I managed to 
trip myself a few times when writing examples. So I got rid of it, and 
introduced an explicit op_result.success() method which does a virtual call to 
the category.

Anyway, just wanted to share.
