I have here a library (it's the client side of a client-server
interface including a pile of class definitions) which has
implementations in pure C++, Java and Python, taking about 3000,
3500 and 1500 loc respectively. And there's an associated module
(with no C++ implementation) that I remember being particular
"impressed" while writing it to find being 3 times as long in Java
as Python despite (a) extensive (and pretty much common) Javadoc/
docstrings and (b) implementing in the Python version a feature
present in the standard Java library (scheduling a thread to run
at specified intervals and time out). Strip the Javadoc/docstrings
out and it's about at that 5:1 ratio.
As for Ruby, looking at some of the comparisons given elsewhere
in this thread, my intuition is that it would be more loc than
Python due to all the explicit end s.
