Subject: Array resizing

Maybe dumb question, but...

I have not found anything like Array.resize, i.e.

a = [1,2]

a.resize(5)     #=> [1,2,nil,nil,nil]
a.resize(5, 3)  #=> [1,2,3,3,3]

I can use Array.fill, but

a.fill(3, a.size, a.size+2) 

looks a bit ugly, not?

Moreover, if I want to resize to size lesser then array is, I need slice.

Why not to have all-purpose resize?

Victor.
