modifiers, a variable can be initialized, overridden, read, assigned,
or bound from within the script only.

def The default access permission is script access; a definition can be

read from or bound to within the script only.

public var Read and writable by anyone. Also, it can be initialized, overrid-

den, read, assigned, or bound from anywhere.

public def

This definition can be read anywhere. A definition cannot be
assigned, initialized (in an object literal), or overridden no matter
what the access permissions. It may be bound from anywhere.
