Make a sequence/1 function that generates a default string

[paulcsmith]

A lot of times I just want a unique value like this:

title: sequence(:title, fn(n) -> "Title #{n}" end)
body: sequence(:comment_body, fn(n) -> "Comment Body #{n}" end)

For simple cases like this I think it would be helpful if you could do something like

title: sequence(:title) #generates "Title #{n}"
body: sequence(:comment_body) #generates "Comment Body #{n}"

Thoughts on this? Would it be better to use Faker or would this be useful?

And maybe the name could be different. Like gen_unique(:title) or something like that

I really like title: sequence(:title). Good idea!

I'd rather it be the same name (sequence) so it's easier to remember / there's less to learn.

Great! This is super easy to implement so I'll add that tomorrow :D

Actually it might make sense to simplify this and make the first arg a string. So you would do:

sequence("Title") # Generates "Title 1"
sequence("Comment Body") # Generate "Comment Body 1"

I think the key can be a binary so that might work better. Less indirection I think
