Go rant

[bearophile]

This is a mostly boring rant against the Go language:
http://monoc.mo.funpic.de/go-rant/

Near the end it contains an interesting bit:
>Too, why this divide, again, with reference types and value types? Did they not learn from the problems this caused in Java? While Java slowly struggles its way free of that tarpit, the Go designers leap in headfirst.<

Can someone here explain me this problem better?
