Cool, thanks.

I've just realized you don't even need the 'nil' to flesh out some=20
syntactically valid functions/methods/case statements that do nothing:

irb(main):005:0> def foobar
irb(main):006:1> end
=3D> nil

irb(main):010:0> x =3D 1
irb(main):011:0> if x =3D=3D 2
irb(main):012:1>   puts "Two!"
irb(main):013:1> elsif x =3D=3D 1 # do nothing
irb(main):014:1> else
irb(main):015:1*   puts "Not 1 or 2"
irb(main):016:1> end
=3D> nil

technically they return nil but that is incidental...
