BEGIN not safe after errors--compilation aborted at (eval 495) line 7.
The problem is that the prototype for atan2() appears to
require two piddle arguments, specifically. Does anyone
know if there is a way to make the above work or is
this a restriction of the current PDL implementation?
Thanks,

Wow, that's a toughy. However, reading the docs, I see this:
Note that when calling this function explicitly you need to supply a third
argument that should generally be zero (see first example). This
restriction is expected to go away in future releases.
So, you could call it like so (note the trailing zero):
PDL::atan2($a->using(0,1), 0)
Very mysterious...thanks for the fix. --Chris
