What's the purpose for last_bound?

Hi guys,

I am curious to understand what is the purpose of last_bound? It seems to just store the last bound data for some reason.

Also, if the next function returns an empty value, then it's replaced with the last bound value. Which is very weird.

It is meant to make bind() function work with function cacheing. The logic isn't very good though now when I look at it, because it has that side effect you mentioned and also it would work only with exactly one bind() in a function.

We need to rethink the approach to this issue, we'll look into it and hopefully come up with a bug fix soon.

@Nomafin thanks for the hot fix, we just updated our codebase and it seems to be working fine now!
