Re: [go-nuts] write func with optional bool return value

I know, so my question is - does it possible to write such functions like builtin? For example I can create func via reflect пт, 27 авг. 2021 г. в 18:03, Levieux Michel : > > Hi, > > Optional returns and parameters don't exist in go, what you are referring to > is built-in behavior specific t

Re: [go-nuts] write func with optional bool return value
