Perl 6 Deep Dive

Meta-operators in Perl 6

So far, we have covered many of the operators that operate on regular operands—values, variables, objects, and so on. In Perl 6, there are operators of another kind—operators that operate over operators. These operators are called meta-operators. We will examine them in the following sections. With some exceptions, every meta-operator can take any regular operator to create a new operation that follows certain rules. Meta-operators also work with user-defined operators, which we will discuss later in this chapter, in the User-defined operators section.
