Besides required blocks, it's possible to place blocks within code, independent of supporting other language constructs. This could be useful if there was an iterative or recursive routine with local variables that weren't necessary for subsequent iterations or recursive calls. By isolating these variables and the data working on them within a block, a local scope can be established where those data items only exist within the scope of that block and aren't carried ...
