You can write library procedures, not primitives. Not everything you can
achieve by a lib. procedure: Try DOTCOL to find what's the color at a
given location, and see that you can't do it as a lib. procedure.

I'm talking about a missing PRIMITIVE that reports the position of a
turtle DIRECTLY, with the need to go phisically to its position.

I don't really know TELL and/or ASK. But try it yourself: How you find
the distance between two given turtles? In my proposed primitive all you
would have to say is:

	PR DIST TURTLE 1 TURTLE 2

("TURTLE" is my suggested name for the primitive, but it can be anything
other).
