Pass by value/pass by reference

[ren90]

Hey Nathan,

Firstly thank you very much for you post. It was really helpful to me, since I was also kinda confused with the best practices for passing args in Go.

In line 74, you talk about pass by mechanisms in Go, which when reading it reminded me of a really interesting article about how this is handled in Go. Maybe you want to make a parenthesis referencing the article for people who are interested, if you think its reasonable. :) It's Dave Cheney's There is no pass-by-reference in Go

Thanks once more, Best regards, R
