You should really read the rc(1) man page. It will answer your
questions.

Here the functions foo and bar are equivalent:

        fn foo {
                <$1 while(l = `{read}) echo $l
        }
        
        fn bar {
                { while(l = `{read}) echo $l } <$1
        }

Think about why this one is not like the others:

        fn baz {
                while(l = `{read}){ echo $l } <$1
        }
