Writing Code

This chapter will prepare you to write Perl 6 code. Before we examine variables, data types, object orientation, and other important topics, let's learn more about how the source code is organized in Perl 6. There are many elements that differ from other programming languages, and it is worth spending time getting used to it.

In this chapter, we will cover the following topics:

• Using Unicode
• Whitespaces and unspaces
• Comments
• Creating Pod documentation
• Phasers
• Simple input and output
