use strings to call functions

Can you tell the difference between your above statement and the following:

"""
eval() is potentially dangerous and can make code harder to debug. 99% 
of the proposed use case for eval() are covered by simpler, less 
dangerous and easier to understand solutions, so the GoodPractice(tm) is 
to favor these solutions and only use eval() - with appropriate care - 
for the remaining 1% _real_ use case.
"""

If you can't tell the difference, then you're about as (im)mature as my 
13 year old son and it might eventually be time to grow up.

Knives - specially the kind I use in my kitchen - are indeed potentially 
dangerous, and I indeed had to educate my son so he wouldn't do anything 
stupid with them - like pointing a knife at someone, running across the 
house with a knife in his hand, or using them instead of a more 
appropriate tool.

The probability that someone will enter your kitchen and use one of your 
knives against you, while not null, are low enough to be ignored IMHO. I 
whish I could say the same about script kiddies or more educated (and 
dangerous) bad guys trying to attack our servers.

But you obviously never had to neither fix a compromised server nor 
raise a kid - else you'd now better. Hopefully you didn't raise my kid - 
now I just pray none of your code will ever run on our servers.
