At this point you may also be wondering why you're printing anything at all, after all you are within a REPL.

The P in REPL means to print, which means that the value of any expression will be printed regardless.

Try the following:
"Hello World!"
Notice the output is the same as printing it. This is due only to the implicit print of the REPL, this does not mean that Perl6 prints the result of every line of code.

Throughout this tour, feel free to simply write the expressions and count on the implicit print.
