And that's why.   You can't use a macro in a function.  You CAN use a function
in a macro.

I think at this point, with a little experimentation, you can work out why the
above doesn't work.

I'm thinking that there's another, weird way to do this using pigment functions
- then it would be possible to use the dot notation, but the syntax is big,
bulky, and something that I wish could be fixed.
