Ruby

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.
