Stupid Ruby Tricks
summary
Shows concrete Ruby tricks: use file.read/file.write instead of manual open blocks, drop optional parentheses but split overloaded lines, and use Hash.new with a block to create default_proc recursive hashes (including swapping the default proc at runtime). Demonstrates prepend vs include and guarding with defined?(super), embeds data after __END for in-file IO, and uses PStore/YAMLStore transactional flat-file DB examples — all snippets run and behave as described.
