Making a shallow copy of a const or immutable value removes the outer layer of immutability: Copying an immutable string (immutable(char[])) returns a string (immutable(char)[]). The immutable pointer and length are being copied and the copies are mutable. The referred data has not been copied and keeps its qualifier, in the example immutable.
An immutable characteristic is any physical attribute perceived as unchangeable, entrenched and innate. The term is often used to describe segments of the population that share such attributes and are contrasted with others by those attributes, and is used in human rights law to classify protected groups of people who should be protected from civil or criminal actions directed against those ...
The Immutability or Unchangeability of God is an attribute that "God is unchanging in his character, will, and covenant promises." [1]The Westminster Shorter Catechism says that "[God] is a spirit, whose being, wisdom, power, holiness, justice, goodness, and truth are infinite, eternal, and unchangeable."
This is persistent because the tail of the list can be taken, meaning the last k items for some k, and new nodes can be added in front of it. The tail will not be duplicated, instead becoming shared between both the old list and the new list. So long as the contents of the tail are immutable, this sharing will be invisible to the program.
In object-oriented programming, "immutable interface" is a pattern for designing an immutable object. [1] The immutable interface pattern involves defining a type which does not provide any methods which mutate state. Objects which are referenced by that type are not seen to have any mutable state, and appear immutable.
Many of these attributes only say what God is not – for example, saying he is immutable is saying that he does not change. The attributes of God may be classified under two main categories: His infinite powers. His personality attributes, like holiness and love. Millard Erickson calls these categories God's greatness and goodness respectively ...
President Trump has issued an order banning federal funding of "indoctrination of children," but his definition of indoctrination is subjective and he is imposing his own views on education, while ...
For example, one could define a dictionary having a string "toast" mapped to the integer 42 or vice versa. The keys in a dictionary must be of an immutable Python type, such as an integer or a string, because under the hood they are implemented via a hash function. This makes for much faster lookup times, but requires keys not change.
