For example, many programming languages provide special syntax for referencing and updating array elements. Abstractly, an array reference is a procedure of two arguments: an array and a subscript vector, which could be expressed as get_array(Array, vector(i,j)). Instead, many languages provide syntax such as Array[i,j].
Operator overloading is syntactic sugar, and is used because it allows programming using notation nearer to the target domain [1] and allows user-defined types a similar level of syntactic support as types built into a language. It is common, for example, in scientific computing, where it allows computing representations of mathematical objects ...
List comprehension is a syntactic construct available in some programming languages for creating a list based on existing lists. It follows the form of the mathematical set-builder notation (set comprehension) as distinct from the use of map and filter functions.
In this example, it's used for instantiating the OUT class, which is the class for the standard output. The + operator has been overloaded by the class to append the string passed as argument to the stream. Operators such as + are syntactic sugar for conventionally named method calls: a + b stands for a.plus(b). The usual arithmetic precedence ...
A similar example was the lock screen command that stopped visual updating, which was a short form for set the lockscreen to true, where lockscreen is a property of HyperCard itself—also a container. Many examples of this sort of syntactic sugar were found in HyperTalk, in order to simplify the syntax and improve readability of common code.
Method chaining is a common syntax for invoking multiple method calls in object-oriented programming languages. Each method returns an object, allowing the calls to be chained together in a single statement without requiring variables to store the intermediate results.
Dads tend to have the most fun hobbies — fishing, golfing, bird watching, and, if you're my father-in-law, storytelling.He tends to be an incredibly fun person to shop for this time of year, but ...
Similarly, ``.l.di first applies .l to .d, printing the letter l and returning .d; this result of .d is then applied to i as in the previous example. The function r is syntactic sugar for the function that prints a newline character. Other important features provided by Unlambda include the k and s functions.
