I'd very much love an easy way to assign a value to an optional variable IF it's nil. Ruby has a ||= operator, which does exactly that.
For example:
foo ||= "default value"
Which basically means:
if !foo {
foo = "default value"
}
It's super convenient for assigning default values to optional arguments.
