LINE_P advanced form question

[keldor314]

Has anyone been successful getting LINE_P to accept a matrix for lines_definitions? I just get a syntax error, and have to use a list instead, which has some nasty performance issues for allocating large lists. TRIANGLE_P accepts matrices for both points_definitions and triangle_definitions, and the documentation for LINE_P suggests that it should work the same way, but I haven't gotten it to work.
