sure?  AFAIR, in Go redefinition is an error... (unless in the same
statement you define another variable for the first time)

Oh, you're right. Idiomatic go error handling depends on being able to redefine variables, to avoid making a huge number of redundant variables. But it'll complain if you don't have a new variable defined with it. http://play.golang.org/p/mX3EaRrEYw

Nonetheless, it does allow redefining variables within a single scope, if with restrictions.
