Code Writing Code, say what now! Meta Programming and PowerShell
summary
Demonstrates Meta Programming in PowerShell by actually generating code not just describing it: reflection and templating handle character escaping and indentation, Array vs ArrayList vs file output shows measurable speed differences, a pester-test generator produces tests for 118 commands into 99 lines, a static robocopy wrapper emits ~583 lines of PowerShell (needs hand-fixes for weird switches), and a real bug story admits a missing switch once drops about half a million rows so sanity checks are mandatory.
