Perl 6 Deep Dive

Functional Programming

Perl 6 is a multi-paradigm programming language. In the previous chapters, we mostly used traditional imperative programming. In this chapter, we will talk about the ways you can use a functional programming style with Perl 6.

These topics will be covered in this chapter:

• Principles of functional programming
• Re-writing traditional programs using recursion
• Reduction operations
• Higher-order functions, lambdas, and the whatever code blocks
• Piping data with feed operators
• Closures, currying, and dynamic scoping
• Lazy and infinite lists and sequence generators

Before we go into any detail of the previously-listed topics, let us talk about what functional programming is.
