Hi All, I have an ugly logical expression, and I just know there's a much nicer, more concise way to phrase this in ruby:

some_variable == 1 || some_variable == 2 || some_variable == 4

All suggestions welcomed, Thanks

If you want to do something conditionally, you can also do:

case some_variable
when 1, 2, 4
    blahblah
else
    blahblah
end
