valuepushIterator

:: LuaError e
=> (a -> LuaE e NumResults)
pusher for the values
-> [a]
list to iterate over lazily
-> LuaE e NumResults

Pushes three values to the stack that can be used in a generic for loop to lazily iterate over all values in the list. Keeps the remaining list in a userdata state.

If the values pusher function returns NumResults 0 for a list item, then this item will be skipped and the values for the next item will be pushed.
