Can you clarify what you mean mean by “the code does exactly what it shows on the page”? How do you know by looking at the code, or even compiling the code, that all possible errors returned by a function are handled? That to me is biggest difficult in reading (or using) others Go code. Exceptions (well written) handle this by declaring all possible error (or categories) thrown by the method.
This seems a real problem with long term maintenance of Go code. > On Feb 20, 2021, at 1:39 PM, Matthew Holiday <matthew.holi...@nytimes.com> > wrote: > > > Roger beat me to it. > > But allow me to rephrase, > > "The users of Go for a long time have resisted any changes to its simple, > clear method of error handling despite it being a major concern of folks who > don't use Go much." * > > * I'm referring to the original survey, which was worded along the lines of > "what keeps you from adopting Go?" > (implying that the responders are those who haven't adopted Go) > > Any type of error handling that creates invisible returns in a function is a > bad idea IMNSHO (an opinion backed up by various researches into the > complexity of exception handling).
