<ruslux> Hi, crystaceans! I do not understand how work type restriction in this example: https://gist.github.com/anonymous/24d8cd91e2b4c9ce93901614933bd242 Why type downcasted?

<asterite> ruslux: like this: https://play.crystal-lang.org/#/r/y5c
<asterite> In general I believe that if an API makes you do those casts and type annotations it probably means it can be designed in a different way without needing that
<asterite> (that is, it should be redesigned)
