Hi Vadim,

thanks for the RFC =E2=80=94 the idea of piping into return is interesting.

One question about semantics: what would be the expected behavior if there
is another pipe operand after return? For example:

$foo |> return |> bar(...);

Would this be a compile-time error, a no-op after return, or is return
intended to be a hard terminal in the pipe chain by definition?

Best regards,
Oleksii
