04:08 <FromGitter> <HertzDevil> if that `else` works then it is a bug and it shouldn't work

04:08 <FromGitter> <HertzDevil> and it, in fact, also doesn't

04:09 <FromGitter> <HertzDevil> ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=614d4f615cfd665e524166bc]

04:09 <FromGitter> <HertzDevil> same error

04:09 <FromGitter> <HertzDevil> but when the `when` clause is a type or constant it expands to `State::TWO == @state` which doesn't depend on `@state`'s type

10:06 <postmodern> is there an easy way to wrap one Iterator class around another? Say I have an Iterator that cycles through Strings of a given length. Then I have another iterator that iteratoes through an Array or Range of lengths. How could I combine the two to iterate over all strings of a set of lengths?

10:45 <FromGitter> <oprypin:matrix.org> postmodern, i don't think there is an easy way. you just create a new class. by this point most languages have generator functions but crystal doesn't.

10:50 <yxhuvud> most languages? I think that is your python heritage speaking. They are not uncommon, but I wouldn't say most languages have them.

10:59 <FromGitter> <oprypin:matrix.org> yxhuvud, C#, JavaScript, C++

10:59 <FromGitter> <oprypin:matrix.org> by volume of usage, most

11:00 <yxhuvud> As opposed to Java, Go, Ruby, C etc, that does not.

12:50 <postmodern> ah fascinating use of Channel to wrap around the yielding method

12:53 <yxhuvud> Hmm. I wonder if it could make sense to implement some way of feeding a channel from an arbitrary iterator without having to continously swap the fiber stacks back and forth.
