I recently ran into an issue with closure types that seems to have no
solution present in the language. In a silly example, say you want to
implement an iterator that wraps an int iterator and adds a value to it:
fn add_nI: IteratorInt(v: I, n: int) - ???
This is naturally expressed as a map
Aha, yes, that would plug the hole. I'm a little worried that there's no
assignee and no milestone listed, and the only mention of a timeline on
that page is a comment of Not until Rust 2.0. Is that comment accurate?
That's a fairly major feature to leave lacking, especially given the
effect of
Hello! The 0.9 release prompted me to poke at my nascent rust code. Very
impressed with the language and the progress since I last looked (0.4
maybe?).
Some questions that I wasn't able to find answers for:
* Is there any built-in way to iterate over all values of a C-like enum?
It's not hard
Oh yes, and one more:
* Why does the do-notation require a function that takes a proc()? Given
that || is the recommended type for HOFs it seems like it would be much
more convenient if it worked with functions expecting a proc() or a ||.
