You're definitely confusing yourself again there somehow.  (f) does
not "enter" anything into the "body" of a variable -- it splits a
string into an array, converting newlines into the breaks between
array elements.  I have no idea where you think dollar signs are
coming from ... unless possibly because "typeset -p" will output array
elements using $'...' quoting if there are certain non-printable
characters in the element?

Again this is not making much sense.  There are only two cases:
Strings with newline characters in them, and array elements where a
blank line might become an empty element if you got there by splitting
a string.  Empty elements generally get removed from argument lists if
you reference the array without proper quoting, especially if you're
forcing an additional layer of interpretation by using "eval", but
they won't be removed from the array itself.
