it would be great to be able to get the coordinate I _would_ be at if I moved forward(x) #40

Instead of needing to move there, record that point, and move back (which slows 
stuff down enormously).

Not quite sure what to call it, or if it is useful enough
generally to add it directly to the Pynguin class, but it's
easy enough to do ...

from math import sin, cos
class PP(Pynguin):
    def getforward(self, distance):
        deg = self.heading
        rad = deg * (PI / 180)
        dx = distance * cos(rad)
        dy = distance * sin(rad)

        x0, y0 = self.xy()

        x = x0 + dx
        y = y0 + dy

        return x, y

Do you have a better name, or an example that makes a great
case for adding the method to the base class?

Mostly, it's come up for when people want to constantly check if they are 
within some shape or region they've made--they go forward 1, check something, 
if it's true, go back, and then actually go forward.

Maybe a name like "peekforward" or something?

I'm not sure it should be in the base class either--it's really a workaround a 
speed issue for a common workflow, I suppose.

Ok. I've done something like that before and it was pretty useful.

I've added the method as:

xyforward(distance)

but I did not pull it in to builtins yet. Give it a try and let 
me know how it works out.

Thanks!  I'll check it out.

Nope, I can't seem to reproduce it.  I'll let you know if it comes up again.  
Thanks!

I went ahead and added xyforward() to the built-in functions
