Hello,

I've come to Racket via Logo, and furtle seems the nicest implementation of turtle graphics I've found in Racket. (I've drawn the "fractal plant" seen on https://en.wikipedia.org/wiki/L-system, and even for n=7 or 8 it was amazingly fast, once I increased the memory limit). However, there are two things I'm still not sure of: (1) saving the turtle's current position and heading, and (2) moving the turtle to a given position and heading.

In Logo (1) would be implemented with POS and HEADING, and (2) with SETPOS and SETHEADING. It may be that these are primitives that don't need special furtle functions, but anyway I don't know how to do either of them.

I'd be happy of any advice! Thank you very much. And thank you for the furtle package!
