If "array substitution" is going to be implemented in the future, my
preference is to use the same variable name, REPLY, in a similar way
as FUNCNAME and PROMPT_COMMAND were promoted from scalar variables to
indexed arrays. Then, one can use the same shell function to get the
first element by ${| fn; } or to get all elements by ${@ fn; } (or
whatever syntax).
