Instance Type Details

Question

I am new to Elm and as a former Haskell programmer, I wonder if there is a way, like in Haskell, to enter the / REPL interpreter:

:i number

So, I know that this does not work in Elm, but is there something that is equivalent to Haskell's:

:i Num

I want to get detailed information about the type class and all its instances.

In addition, the Haskell documentation contains information on the hierarchy of Haskell base class types:

https://www.haskell.org/onlinereport/basic.html

Is something like this available for Elm too?

Thanks in advance.
