And PowerShell has a built-in called start. I used the .bat suffix to distinguish Invoke-Expression from Interactive Elixir, but this works too:
start iex --werl
Executables are case-insensitive under Windows. Given a choice, I’d rather have the PowerShell builtins also be case insensitive than have exes and builtins disagree.
Also, having executables on your system with names that differ only in case is a serious system configuration smell.
