See http://docs.python.org/library/ast.html#ast.NodeTransformer
Replace any Expr node in the ast tree with a function call to
{{{
def __print_if_not_none(expr):
if expr is not None:
print expr
}}}
An Expr node is anything like
{{{
123
do_foo()
for i in range(10):
i
}}}
Which will be replaced by
{{{
__print_if_not_none(123)
__print_if_not_none(do_foo())
for i in range(10):
__print_if_not_none(i)
}}}
Which will output
{{{
123
0
1
...
9
}}}
