Perl Programming Documentation, also called perldoc, is the name of the user manual for the Perl 5 programming language. It is available in several different formats, including online in HTML and PDF. The documentation is bundled with Perl in its own format, known as Plain Old Documentation (pod).
A pod parser always assumes that the file it is parsing doesn't start with pod; it ignores all lines until it sees a pod directive. pod directives must come at the beginning of a line, and all begin with an equal sign.

The second line in the canonical form includes a semicolon, which is used to separate statements in Perl. With only a single statement in a block or file, a separator is unnecessary, so it can be omitted from the minimal form of the program—or more generally from the final statement in any block or file.
In line dancing the term chassé is used for a triple-step sequence in any direction (forward, side, back, diagonally, or curving). For instance, if the chassé is to be done to the right, the right foot steps right, the left foot is placed next to the right, with the weight being transferred to the left foot so that the right foot can complete ...
