Dir cannot be called with an array argument
The documentation for
Dir claims that it can be called with an array and it will behave like Dir.glob:
Dir[ array ] → array Dir[ string [, string ...] ] → array Equivalent to calling Dir.glob(array,0) and Dir.glob([string,...],0).
However, doing so raises a TypeError:
$ ruby -e "puts Dir[['/bin/bash']]" -e:1:in `': no implicit conversion of Array into String (TypeError) from -e:1:in `<main>'
Dir.glob works as documented:
$ ruby -e "puts Dir.glob ['/bin/bash']" /bin/bash
I'm unsure if this is supposed to work as described or if it is a documentation bug, but it is reproducible on 2.0, 2.1, and trunk.

I'm aware of what actually works in practice, but the documentation claims both forms are acceptable:
Dir[ array ] → array Dir[ string [, string ...] ] → array

Dir.globallows an array but
Dirnot. the former accepts an optional parameter

flags. [ruby-core:65265] [Bug #10294]
