Actually... as one with the vested interest...

I'm not opposed to entering an equation in one of the basic algebraic forms. Given 
that line types and line segment types both exist, I'm happy to weigh the cost/benefit 
between choosing an lseg and entering 2 points, or choosing a line and entering the 
equation.

Are there database functions to translate between a line and a line seg? If so, that 
would address my only reservation for restricting the line type to an equation. And - 
to address Tom's continuing concern over casting ;), I have no need for implicit casts 
in this case.

If there are concerns about precision being lost in the translation - As long as what 
precision can be guaranteed is documented, I have no qualms. If I needed absolute 
precision I'd create my own line table with numerics, and write my own functions as 
necessary. The line type to me is there for speed and ease of use, not unlimited 
precision.
