Control Flow

In this chapter, we will be talking about the main elements in controlling the flow of programs in Perl 6. Most programs are not just a list of instructions, but they should rather react to user input, take decisions based on calculated data, and so on.

In this chapter, we will cover the following topics:

Code blocks and the do keyword
Conditional checks
Loops
Breaking the loop body
Collecting data using gather and take
Setting the topic
Executing code only once

Shitov

Andrew Shitov has been a Perl enthusiast since the end of the 1990s, and is the organizer of over 30 Perl conferences in eight countries. He worked as a developer and CTO in leading web-development companies, such as Art. Lebedev Studio, Booking dotCom, and eBay, and he learned from the "Fathers of the Russian Internet", Artemy Lebedev and Anton Nossik. Andrew has been following the Perl 6 development since its beginning in 2000. He ran a blog dedicated to the language, published a series of articles in the Pragmatic Perl magazine, and gives talks about Perl 6 at various Perl events. In 2017, he published the Perl 6 at a Glance book by DeepText, which was the first book on Perl 6 published after the first stable release of the language specification.
