Avoid instanciation with new

Why you should care

Use &T{} instead of new(T) when initializing struct references so that it is consistent with the struct initialization.

How we detect

CAST Highlight counts one occurrence each time the keyword “new” is used.

// Bad
sptr := new(T)
sptr.Name = "bar"

// Good
sptr := &T{Name: "bar"}
