I've long held that the python string quoting styles “just work” and we should
appropriate them rather than reinventing the wheel. In particular, the
ability to write raw strings such as
r'something containing backslashes (\) and quotes (")'
and
r"""something containing backslashes (\), quotes (") and
newlines!"""
economically is extremely useful.
When one needs to embed a fairly large block of text in source, the
ability to use the triple-quoted forms *without* injecting noise on each
line is fantastic.
