Ah. I think I understand what you mean. Jelly adds the ${foo} decorations
to allow the distinction between references and constants, and to not
inflict one kind of indicator. So jelly uses ${foo}, but others could do
$foo, %foo, <foo>, etc... Jexl accomodates all by not inflicting one way on
the user.
If you wanted a constant string 'name', then just put single or double
quotes around it...
'name'
Does that address what you were saying? (I am wondering if I missed your
point...)
