Elegant way of creating an array of arrays?

I want to create an array of arrays from another array:

a = [11,1,[23,21],14,[90,1]]
a.map { |e| e.is_a?(Array) ? e : [e] }
# => [[11], [1], [23, 21], [14], [90, 1]]

Is there an elegant way to do this?

I would do as below :

a = [11,1,[23,21],14,[90,1]]
a.map { |e| [*e] }
# => [[11], [1], [23, 21], [14], [90, 1]]

or using Kernel#Array()

a.map { |e| Array(e) }
# => [[11], [1], [23, 21], [14], [90, 1]]

Use, which ever you think as elegant, for me both are elegant :-)
