+Certain Ruby language features are shorthands for common operations that could also be expressed in other, more verbose, forms.
 Such language features are typically referred to as "syntactic sugar", and make it easier for programmers to write and read code. This is

 rich syntactic constructs into equivalent code that uses simpler syntactic contructs.
 
 For example, supposing that ``x`` is an object with an attribute ``foo``, the assignment::
