I find |> annoying to type. How about making it so unary functions can be invoked like this?

  arg function_name

Then instead of

  arg |> func1 |> func2 |> func3

you could simply write

  arg func1 func2 func3

It might get a bit ugly when used with arrow functions instead of named functions, and there might need to be a special case when arg is a function, but if those problems could be handled not too unreasonably this seems a fine approach for a programming language.
