Actually Go's use of := is almost anti-pascal: it means something rather different, but similar enough to be confusing, and so is likely to confuse anybody who's used to the vastly more common meaning of := in Algol-family languages (Pascal, Ada, etc).

... and then there's Go's screwed up version of Pascal-style declaration syntax...

[a link to my earlier rant on this subject: http://news.ycombinator.com/item?id=4520104 (TL;DR: Go: "var foo, bar int"; Pascal: "var foo, bar : int"; the colon vastly improves readability, and has no real drawback)]

Go's declaration syntax (http://golang.org/doc/articles/gos_declaration_syntax.html) and package system are inspired by the Pascal family, according to the FAQ (http://golang.org/doc/faq#ancestors).
