TypeError: reduce() of empty sequence with no initial value

[povilasb]

from functional import seq
seq([]).reduce(lambda res, n: res + n)

results in

TypeError: reduce() of empty sequence with no initial value

Sequence.reduce() could accept third optional variable "initial value" as python functools.reduce() do.

What do you think? :)

Thanks for taking the time to open an issue! I agree that this would be useful and reasonable. I'll spend some time this weekend to implement something.

Great, thanks:)

@povilasb Finished implementing that in latest commit. I added tests, but would be great to see if it works as you're expecting before closing the issue.

Works as expected, thank you :)

Nice. I'll got ahead and close this then. I'll look to see when I could do a release, but so far this would be the only thing going in. It would be nice to do a release that has a few more improvements in addition to this one.
