Comments are parts of the source code, which are ignored by the compiler. Comments are intended to give additional information about the program itself. Good examples of comments are explanations of the algorithms used, or the purpose of variables, or a description of the input arguments of a function.
Perl 6 offers two ways of saving additional human-oriented information in the source code by using comments and the so-called Pod. First, we will examine the comments.
Comments are fragments of source code that a compiler does not consider as direct instructions for...
