I once suggested something like that to Jack (right after my first
encounter with the problem ;-) and he didn't sound too thrilled. I'd
already be *very* happy if it would raise a more descriptive error, instead
of the rather vague:

  File "DevDev:JustPy:unixfiletest.py", line 1
     sys.stdo    sys.stdout = s#raw_input("--usb2x, b2y)1y, a2x,lccu    b1y
= a1y + 2.0*(by- return b1x, b1y    magic = calcQmagic(pi/2))/3   midx =
radius:xoffset + radius * m    b2y = yoffse + xoffsetdy = radius *
cos(pi/4) + yoffset  y = yost + radius * magic - radiusff print B1x, B1y,
Boffset, yoffset,   mx, midy, b1x, def   b1y = yoffset     x = b2xc():agic
= ca  print "def dra    for i in ran     x = ra     print x, y, "l".5 * pi
* (i+1)) / segmentsngle          tprint "S"t = sys.stdoutsymain()u     dr
finally:", "w")e()c()ter-")
                      ^
SyntaxError: invalid syntax



Or something. (And it takes forever to print that, since python thinks the
whole file is *one* line, and thinks it has to show the line with the
Syntax error)
