Multiline string literals

[Peter Reilly]

Thanks for the update!
my google powers are pretty poor ;-)

I do not agree that """ is IDE unfriendly, at
least in the sense that is is supported by
the three main java ides (for groovy), and in theory any editor
that supports python.

Back in 2006 (yicks, is it that long ago), I hacked
the javac compiler to add support for """ multiline support,
it was ridiculously easy  - see
