Classes are specified to have an immutable inner binding even if they
also declare a mutable lexical binding in the enclosing scope:
class Foo {
foo() {
// immutable inner binding 'Foo' is in scope here
}
}
// mutable lexical binding 'Foo' is in scope here
Having two bindings can be tricky. Suppose I then do this:
Foo = wrapConstructorWithExtraLogging(Foo);
Now the two bindings have different values. If one of Foo's methods
does `new Foo`, we don't get the extra logging.
Can we go back to having classes do what functions do? A single
function never introduces two bindings; rather a named function
expression has only the immutable inner binding and a function
declaration only declares a variable.
