The error seems awesomer now​:

dir | say #bug too ?

Failed to get the directory contents of 'True'​: readdir failed​: No such file or directory

dir(".") | say "a"
a

Closable with tests?

Dare I ask what it stringified True to? What happens if the user has a
directory with that name? Granted, POSIX says it should fail if it's the
empty string... but that's only POSIX, and I'd be inclined to consider it
an accidentally safe result.

Seems to be much better now​:
