Yikes, I had not expected this:
```
Date.fromString "Cisco 6807"
Ok <Mon Jan 01 6807 00:00:00 GMT+0100 (Central European Standard Time)>
: Result.Result String Date.Date

The problematic package was: thebritican/elm-autocomplete. In the issues on github I found that it had been forked to: ContaSystemer/elm-menu. I've now installed the latter and the installation succeeded

I see. That package itself is for Elm 0.18 (you can be sure of it whenever you see `elm-package.json` and don't see `elm.json` in the source) so I am wondering why `elm install` did not say anything about it

Why, yes, there are many resources for new developers ; one which will guide you through the process of discovering and building a few examples is the official documentation, it's easy to read and encourages you to practice to get the basics.

Yeah, not all browsers will do that. Hence why `Date.fromString` was removed in 0.19 - it's not a pure function, since it depends on (a) browser and (b) timezone. So with the same input, that function can return different things in different clients. Pretty annoying!

<@Salvador> `elm/html` doesn't expose the `Html msg` type in a way that it can be converted in to a string. But <https://package.elm-lang.org/packages/zwilias/elm-html-string/2.0.1/> provides a similar API and has a `toString` function

I saw that, but it doesn’t help as you can not turn an `Html.Html` into an `Html.String.Html`, unless I missed something.

Yeah, it requires changing your imports - there's no way to convert `Html.Html msg` into anything, since it's an opaque type

I've got this aliasing going on:

This `roundEach` call produces:
#Attribute msg#

#Attr decorative msg#

For example, if my list is filled with `Attr Int Msg` and I want to add an `Attribute Msg`, I will attempt to add an `Attr () Msg` in a list of `Attr Int Msg`.

So, if you want your list to remain unbound, you can't put an `Attribute Msg` inside.

the list:
```
[ Background.color skin.primaryColor

{ topLeft = 5

```
the types:
`color : Color -> Attr decorative msg`
```
roundEach :
{ topLeft : Int
, topRight : Int
, bottomLeft : Int
, bottomRight : Int

-> Attribute msg
```
|
2019-02-12T09:58:54.163300

`color` does not bind the `attribute` type variable, so I would assume it will be bound to `()`

it could use some polishing, ie. caching the intermediate calculations inside the Animating record and just multiplying the delta by that on each tick
