Hello, This is misleading. With default arguments, there remains only one function definition, which makes it quite different from function overloading where there would be multiple definitions. Default parameters provides syntax sugar at the call site, but does not create additional functions.
I'm not arguing for default parameters. The explanation in https://talks.golang.org/2012/splash.article#TOC_10 is good, given Go's philosophy.
