Re: How to find if a drive letter exists?

Why do you have `.Bool` on all of the `.e` tests? A file or directory either exists or it doesn't. So `.e` always returns a Bool. So there is zero reason to try to coerce it to a Bool. You can look at the return value of `.e`. > say '.'.IO.can('e').head.signature (IO::Path:D: *%_ --> Boo

Re: Different return values with "say" vs "put" (Nil representation... )
