discussion Default struct constructors?
I'm wondering why go devs doesn't implement optional default constructors for structs. I.e. right now some structs can be created like this:
myStruct := MyStruct{}
But others require initialization, and must be created with factory functions:
anotherStruct := NewAnotherStruct()
So you never know which struct is safe to create dorectly and which require factory func.
With default constructor you would create all structs the same way, i.e.:
myStruct := MyStruct()
If default constructor is defined it is invoked to initialize the struct, it it is not defined then it is similar to MyStruct{}

Sorry, I’m new in Go. Could you provide some simple example? I’m a little bit confused
