In Ruby can I shortcut checking if a variable is nil and replace by a default value?

Is there a way to shortcut checking if a variable is nil, and give a default value if it is?

For instance, replace

result = (var == nil ? defaultvalue : var)

by something like

result = selfifnotnil(var, default)

Of course I could write selfifnotnil function like the ternary above, but is there any built in option?
