Very new to Elm but wanted to play around with the <~ operator. It seems when I run elm-make, <~ it is not recognized as an operator, and I get the error
Cannot find variable
<~
Has this been deprecated ( I see it in the docs at elm-lang.org/docs/syntax#mapping ). Am I just using it incorrectly? Here is my code snippet that will not compile-
sqrtSig : Signal number
sqrtSig = sqrt <~ Mouse.x
Yes, <~ and ~ were removed following this discussion
