Do you mean "shouldn't it be documented in the manual"? If so, I agree. 
I'll be sure to explain this in the manual alongside my patch to add 
support for piping to Lisp functions in Eshell. (It seems better to do 
it all at once since if I updated the manual now, I'd probably have to 
update those parts again to account for the pipeline changes.)
