[pygame] Speed *triples* by changing 'apply(f, args)' to 'f(*args)'

Hi,

I was having troubles with a low framespeed. In my game,
1/3'rd of the time was in the warn() function:

         84811 function calls (84805 primitive calls) in 11.340 CPU seconds

   Ordered by: cumulative time
   List reduced from 159 to 10 due to restriction <10>

   ncalls  tottime  percall  cumtime  percall filename:lineno(function)
        1    0.020    0.020   11.340   11.340 brian.py:169(main)
        1    0.000    0.000   11.340   11.340 <string>:1(?)
        1    0.000    0.000   11.340   11.340 profile:0(main())
        1    0.060    0.060   10.150   10.150 brian.py:89(mainloop)
       80    1.930    0.024    7.960    0.100 sprite.py:305(update)
    24084    2.910    0.000    4.810    0.000 warnings.py:16(warn)
    24084    1.890    0.000    1.900    0.000 warnings.py:51(warn_explicit)

This game ran at 3 fps with profile, 6 fps without. Note that it ran approk,
80 frames and warn was called 24000 times.

Then I changed in sprite.py:311, apply(f, args) to f(*args).
Framespeed tripled:

         39894 function calls (39888 primitive calls) in 5.790 CPU seconds

   Ordered by: cumulative time
   List reduced from 151 to 10 due to restriction <10>

   ncalls  tottime  percall  cumtime  percall filename:lineno(function)
        1    0.000    0.000    5.790    5.790 brian.py:169(main)
        1    0.000    0.000    5.790    5.790 <string>:1(?)
        1    0.000    0.000    5.790    5.790 profile:0(main())
        1    0.040    0.040    4.590    4.590 brian.py:89(mainloop)
       88    0.860    0.010    2.200    0.025 sprite.py:311(update)
       87    0.010    0.000    1.430    0.016 screen.py:64(drawbg)
       87    1.420    0.016    1.420    0.016 util.py:264(tiled_blit)
        1    0.000    0.000    1.160    1.160 level.py:113(__init__)
      128    0.030    0.000    1.090    0.009 level.py:124(randsprite)
      441    0.040    0.000    0.980    0.002 level.py:48(addsprite)

Now, it runs at approx. 9 fps with profile, and 18 without (still
unacceptable, but understandable).

Well. It seems warn() is being called but I don't receive warnings
to the console. I cannot explain this, but I noticed it.

This is Python 2.3a2.

yours,
Gerrit.
