trying to get to work with matrices . . .

Added vcat and row to standard_expression_forms

This is my attempt to fix the issue I've raised.

So far I got it to work like this:

prog = "function mtx(x1,x2,x3,x4) \n [x1*x4 x2; x3 x1*x4] \n end"
ex = parse(prog)
exx = cse(ex)

with ex, and exx being:

julia> ex
:(function mtx(x1, x2, x3, x4) # none, line 2:
        [x1 * x4 x2; x3 x1 * x4]
    end)

julia> exx
quote
    function mtx(x1, x2, x3, x4)
        ##*#665 = x1 * x4
        begin  # none, line 2:
            [##*#665 x2; x3 ##*#665]
        end
    end
end

I'm not sure if this will work when called as a macro, but this seems to work at least for my use case above...

Very cool, thank you! Could you add a test for this behavior as well?

Sure, will do (try, new to Julia) sometime this week.

No problem, and thanks! I'm happy to help if you have any questions.
