I would like to manipulate structs at Runtime.
For example, I have a struct:
type Item struct {
SomeField string
}
Is it possible to add field on runtime? Or Access Attribute that is not yet defined. Something like pythons __getattr__() or __call__() so I could dynamically control the fields/methods accessed.
E.g. do something like Item.DynamicField or Item.DynamicMethod() where I don't know exactly the Field or the Method that will be accessed/called, So I can't define it statically.
Maybe I'm missing something in the Reflect package?
Thank you.

The purpose of reflections package is to make developers life easier when it comes to introspect structures at runtime. Its API is inspired from python language (
getattr,setattr,hasattr...) and provides a simplified access to structure fields and tags.

No. Go is a compiled language with statically defined types. You probably need a map if you want to dynamically add properties.
