Go

About

Go has:

garbage collection,
a package system,
first-class functions,
lexical scope,
a system call interface,
and immutable strings in which text is generally encoded in UTF-8.

But it has comparatively few features and is unlikely to add more. For instance, it has:

no implicit numeric conversions,
no constructors or destructors,
no operator overloading,
no default parameter values,
no inheritance,
no generics,
no exceptions,
no macros,
no function annotations,
and no thread-local storage.

To avoid design complexity

Object

Go has no class hierarchies, or indeed any classes; complex object behaviors are created:

from simpler ones by composition,
not by inheritance.

Methods may be associated with any user-defined type, not just structures, and the relationship between:

concrete types
and abstract types (interfaces) is implicit,

so a concrete type may satisfy an interface that the type’s designer was unaware of.
