The curry method was added in Ruby 1.9.1. (examples taken from the documentation).
<lang ruby>
b = proc {|x, y, z| (x||0) + (y||0) + (z||0) }
p b.curry[1][2][3] #=> 6
p b.curry[1, 2][3, 4] #=> 6
p b.curry(5)[1][2][3][4][5] #=> 6
p b.curry(5)[1, 2][3, 4][5] #=> 6
p b.curry(1)[1] #=> 1
b = proc {|x, y, z, *w| (x||0) + (y||0) + (z||0) + w.inject(0, &:+) }
p b.curry[1][2][3] #=> 6
p b.curry[1, 2][3, 4] #=> 10
p b.curry(5)[1][2][3][4][5] #=> 15
p b.curry(5)[1, 2][3, 4][5] #=> 15
p b.curry(1)[1] #=> 1
