Is there a way to make generated data optional?

[lexuzieel]

Sometimes it is useful to generate randomly optional fields, such as the last name (but really - almost any field).

Is it possible to do something like this:

firstName := faker.FirstName()
lastName := faker.Optional(.5).LastName() // <-- Generate non-empty last name 50% of the time

fullName := firstName
if lastName != "" {
    fullName += " " + lastName
}

println("Hello, " + fullName + "!")

Here faker.LastName() would return empty string 50% of the time.

Is it possible to use a custom generator faker for that?
