This software class represents a pawn in a game of chess.
Using the class is straightforward. You can create a new pawn object with its starting position and a label identifying it as one of the "White King's pawn", for example. From there, you can check if the pawn can reach a specific square with the "can_reach" method.
For example, if you want to see if the pawn at "e2" can move to "e4", simply call the "can_reach" method with that argument. If it's possible, the method will return true. You can test other moves as well, such as "e3" or "f3".
Of course, there are some moves that a pawn can't make, such as jumping directly to "e5" from "e2". In that case, calling "can_reach" with that argument would return false.
One neat feature of Chess::Piece::Pawn is the ability to promote a pawn to a different piece, such as a queen. This can be done with the "promote" method, which takes the name of the piece you want to promote to as an argument.
Overall, Chess::Piece::Pawn is a useful and well-designed class for representing pawns in a chess game. If you're building a chess program with Perl, it's definitely worth considering.
