Try using a colon here....

Overall it seems to me that ther must be a better way to do such a thing -
even in C. AFAIK it supports multiline-stringliterals. Why don't you do
something like this:

script = "\
def foo():\n\
    return 'FooBar'\n\
x = title()\n\
print x\n"

And then read that script line by line, feeding it to the parser. Or maybe
the parser even groks that string at once - don't know that.
