Elm 的 (<~) 功能去哪儿了？不再在信号模块中
Where did Elm's (<~) function go? No longer in Signal module
我正在查看 http://elm-by-example.org tutorials. import Signals exposing ((<~)) no longer works in elm-lang/core 3.0.0, and I see in the Elm package documentation，发现此功能已从信号模块中删除。它去哪儿了？
这是完整的类型签名：
(<~) : (a -> b) -> Signal a -> Signal b
(<~) 根据 changelog, because Elm generally discourages infix operators. See also original proposal 从 Elm 0.16 中删除，以弃用 (<~) 和 (~).
您仍然可以找到 (<~) and (~) in Apanatshka's elm-signal-extra 图书馆。
