This problem should already be solved in the newest CVS version of pytables 
(just a little past 0.9.1, I think). A little while ago, it was the first 
step to allow non-pythonic names in the first place. Now it would be the 
second step to make it more convenient to access such names.

Exactly. Especially the name-completion feature in certain interactive shells 
(e.g. ipython) really work together very well with natural naming. This will 
never be possible with other access methods.
