Yeah. :)

BTW, there are at least 2 reason not to use MLCAD to create parts which you want
to contribute to LDraw.org:
1. (General reason) it's more work than doing it in an enhanced text editor.
2. (Specifically) MLCAD does things to the file that are not allowed in official
part files, so you have to clean up the code afterwards (and then you can no
longer edit it in MLCAD).

I don't know if this helps, but we already have language to support this
concept. The LDLite language extensions support the definition of named points
and matrices (and colors, but that's not so useful in this context). In LDLite
code, you can create a file like:
0 POINT A1 10 0 10
0 POINT B2 -10 -10 -10
0 POINT C3 0 -10 0
0 POINT D4 10 -10 10
3 1 A1 B2 C3
3 2 B2 C3 D4
Even if the user were not aware of the point-names, I could see this format
being useful for programs that use point-lists.
It also typically results in smaller files than straight DAT code.
