YAML looks to me to be completely insane, even compared to Python
lists. I think it would be great if the Python library exposed an
interface for parsing constant list and dict expressions, e.g.:
[1, 2, 'Joe Smith', 8237972883334L, # comment
{'Favorite fruits': ['apple', 'banana', 'pear']}, # another comment
'xyzzy', [3, 5, [3.14159, 2.71828, []]]]
[ ... ]
Note that all the values in the above have to be constant literals.
Don't suggest using eval. That would be a huge security hole.
I'm probably not thinking deviously enough here, but how are you
going to exploit an eval() which has very tightly controlled
globals and locals (eg. eval(x, {"__builtins__": None}, {}) ?
See, for example, Alex Martelli's post in an old thread from 2001:
