An observation from under the hood.
Let’s say someone has built a system that has the ability to report the status of a given action using a series of differentiating error codes. You might assume that the person who built said system would encourage the use of those error codes in order to offer feedback to the user and otherwise communicate function or state changes within complex dynamic environments. You also might assume that the error codes would be documented somewhere and that you could easily access them without too much additional effort in order that your own functions could benefit from their use. You might assume these things, but you’d be wrong.
