show-doc Array : no docs found

[LunarLanding]

What I do ( in pry ): show-doc Array
What I expected: the documentation that Yard has for Array.
What happens: no docs found.
What I found about this issue: pry/pry#960
Examples:

[1] pry(main)> ? Array
Error: No docs found for: Array
[2] pry(main)> ? ::Array
Error: No docs found for: ::Array
[3] pry(main)> ? :Array
Error: Couldn't locate a definition for :Array!
[4] pry(main)> ? ::Array
Error: No docs found for: ::Array
[5] pry(main)> ? Kernel::Array
Error: Cannot locate this method: Array. (source_location returns nil)
[6] pry(main)> ? Kernel#Array

From: object.c (C Method):
Owner: Kernel
Visibility: private
Signature: Array(arg1)
Number of lines: 5

Returns arg as an Array.

First tries to call to_ary on arg, then to_a.

   Array(1..5)   #=> [1, 2, 3, 4, 5]
[7] pry(main)> exit
