Hearing this leaves a bad taste in my mouth, because one of the (mis)features I've found in Go is its implicit default value in struct initialization. In Go, you don't get a compile error when you miss some fields while initializing a struct. e.g.
type T struct {
a int
b string
c float64
}
t := T{c: 1.5}
will happily set `t.a` to 0 and `t.b` to an empty string. While this is useful for maintaining backward compatibility (adding more fields to a struct doesn't break upstream code), it also hinders discovering genuine mistakes at compile time. So typical Go programs end up using 0 or an empty string as a sentinel value. This is probably what made me feel Go's dynamic nature the most. It really is pretty close to a dynamic language.
