I don't know one. I guess the low-level syntax parser needs a subscript to be preceded by a matrix or variable name and tweaking it so this could be understood is more bother than it's worth. As you know, you have to worry about what such a change might break.

Thanks, but as the subject line says, I want to
reference e(matrix) directly - I just gave one
example. I've been using the below method for years,
so I hardly think about it anymore, but every once
in a while wonder if there's a shorter way.
