possible bug?

By using := in the following places, I suppose the err variable declared in the return list is shadowed:

fuse/mount.go

Line 41 in cd39596

fi, err := os.Stat(dir)

fuse/mount.go

Line 63 in cd39596

dev, err := mount(dir, config, ready)

fuse/mount.go

Line 76 in cd39596

connection, err := newConnection(

Isn't this a bug or I missed something?

This is a “feature” of Go. There is no shadowing in this scenario.

https://golang.org/ref/spec#Short_variable_declarations

Unlike regular variable declarations, a short variable declaration may redeclare variables provided they were originally declared earlier in the same block (or the parameter lists if the block is the function body) with the same type, and at least one of the non-blank variables is new. As a consequence, redeclaration can only appear in a multi-variable short declaration. Redeclaration does not introduce a new variable; it just assigns a new value to the original.

I see, I don't know why I (wrongly) assumed function result vars live in a separate scope.
