Thanks for the explantation about BOARD_ACTIONS, it looks clean.

I've been implementing a couple of nice things over DLIST, that now can
be iterated with standard python loops, also the BOARD_ITEM/EDA_ITEM
polymorphic class is handled in a very natural way, with the extended
.Cast() method
(implemented in BOARD_ITEM from .i, no cpp modification for that).

from pcbnew import *
pcb = LoadBoard(filename)

ToUnits=ToMils
FromUnits=FromMils

print "LISTING VIAS+TRACKS:"

for item in pcb.GetTracks():  #internally calls .Cast() at each
iteration of the tracks list

	if type(item) is SEGVIA:

		pos = item.GetPosition()
		drill = item.GetDrillValue()
		width = item.GetWidth()
		print " * Via:   %s - %f/%f "%(ToUnits(pos),ToUnits(drill),ToUnits(width))
		
	elif type(item) is TRACK:
		
		start = item.GetStart()
		end = item.GetEnd()
		width = item.GetWidth()
		
		print " * Track: %s to %s, width %f" %
(ToUnits(start),ToUnits(end),ToUnits(width))
		
	else:
		print "Unknown type	%s" % type(item)

Here we can start to work with the magic of dynamic typing in
scripting languages
