line continuation when initializing 2d waves

When trying to initialize a 2D wave in a function (Igor 7), it seems like I can only use line continuation in certain places without causing syntax errors. The last line below (wave foo5) is what I would like to do to format things nicely, but it seems I need to use less-readable line continuation as for foo4.

function foo()
    Make/O foo0 = {0,1,2,\
                        3}              // a line continuation after this comma works for 1D waves
    Make/O foo1 = {{0,1,2,3},{0,1,2,3}}     // here's a 2D wave
    Make/O foo2 = {{0,1,2,3},{0,\
                          1,2,3}}       // line continuation after comma: no error
    Make/O foo3 = {{0,1,2,3},{0\
                         ,1,2,3}}       // line continuation before comma: no error
    Make/O foo4 = {{0,1,2,3},{\
                        0,1,2,3} }      // line continuation after braces: no error
    Make/O foo5 = {{0,1,2,3},\
                       {0,1,2,3}}       // syntax error:  most readable - line continuation between elements
end


It's only a code readability issue, but it would be nice if this could be fixed...
I definitly second your wish!

Interesting is also that the syntax error after comma is not general.

The following

function foo()

    ModifyGraph rgb=(0, 0,\
     1), mode=4
end


does work.
