So what should go?

(a) Here strings: use "echo 'foo' | bar" instead of "bar <<< 'foo'".
For more complex cases, like "bar <<<[0]'foo0' <<<[1]'foo1'" use "echo
'foo0' |[1=0] { echo 'foo1' |[1=1] bar }"

(b) The flattening operator: use a function instead

   fn flatten {
      if ( ~ $#* 0 ) {
	 echo >[2=1] 'usage: flatten list ...'
	 return 1
      }
      list = $1 {
	 shift
	 $list = $1
	 while ( ! ~ $#* 0 1 ) {
	    shift
	    $list = $list^' '^$1
	 }
      }
   }

(c) `` backquote substitution: use

   ifs = ( foo ) { bar = `{ baz } }

(d) newpgrp: use a wrapper around rc.

(e) cdpath: do it with a function.
