In Go, given struct type T, what is the difference between new(T) and &T{}?
Extending @Doug answer:
The two forms new(T) and &T{} are completely equivalent: Both allocate a zero T and return a pointer to this allocated memory. The only difference is, that &T{} doesn't work for builtin types like int; you can only do new(int).
There is no difference. According to Effective Go, they are equivalent.
As a limiting case, if a composite literal contains no fields at all, it creates a zero value for the type. The expressions new(File) and &File{} are equivalent.
