the Go code has MORE functionality (flag parsing) with LESS code. yes its not as fast, and yes the executable is larger, but for many, thats a good tradeoff for the extra standard library features, and the reduced LOC/code complexity. sadly as of yet, I haven't seen any cogent technical arguments against my points thus far.
Your code does not have more functionality than GNU's yes as written. It's less code you have to write because of the flag parsing code that has already been written, and it's incompatible with GNU's yes because yours requires -m to change the message.
it has flag parsing
I'm genuinely curious to hear your argument.
previous comments have demonstrated this not to be the case, so I will stand by my previous points. I have already made over 10 comments on this one topic, so if any aren't already convinced, they never will be, either because they disagree with the tradeoff, or they just have stockholm syndrome for C.
