FEATURE: defer?

[noonien]

Concurrency examples use a waitgroup, but have to do wg .done at the end of the function. This is not a problem if there are no returns, but once there are multiple returns, the user has to have a wg .done before each return.

Due to how functions are created, I'm guessing implementing defer is not very complicated and would add a lot of value, with IO as well.

Frankly, I haven't taken the time to figure out how defer works internally in Go and if we could use that or "simulate" on our own side. I will check it out, thanks!

First version of defer is comming with next big update v0.0.90.

First version of defer was added with v0.0.80. It works for functions but I still see some edge cases that I will work on before 0.0.90.

Thanks for the issue, with this I'm closing it.
