It's too complex. It just special symbol to identify next _expression_
is function like quotes or braces.
Not at all, it simplifies a lot of things. It's not just syntaxic sugar like what you propose (which is incoherent) but implements the mathematical composition and filters. It allows functional programming, it can be used for multi-layered parsers, for safe I/O, for handling errors as return values instead of exceptions.
What you propose is just syntaxic sugar, but with additional ambiguities.
