⚡️ You Might Not Need Gems
summary
Argues that many common gems are unnecessary because Ruby’s standard library already covers them and demos five concrete tools with working examples: delegate/simpledelegator used to build a logging decorator that intercepts every method call and prints method name and args, forwardable forwarding user.name to profile.name, OptionParser help for free parsing --name and printing hello with no extra gem, and REXML (pure Ruby) plus mentions shellwords and singleton; each example runs and produces the expected output.
