Dynamically instantiating types

[tomwilde]

Is there a way to reference a user-defined type and then instantiate this type dynamically in Go?

An example could be:

    type MyType struct {

        Name  string

        Active bool

    }

    func (m *MyType) SetName(n string) {

        m.Name = n

    }

1.- How could I store a reference to this type?

2.- How can I create instances of this type by using the reference?

Brad suggests considering reflection, but another way to do something
that might be like what you want is to use functions -- you can write a
make-me function for the type and pass that around and call it when
you need to generate a value

func makeMyType() interface{} { return MyType{...} }

Thank you very much Peter. I was able to continue coding with your example.
