Underscore ("_") in numeric literals

[pipex!sunic!news.lth.se!dag@uunet.uu.net (Dag Bruck)]

I would like to know to what extent people use undescore ("_")
characters in numeric literals, e.g., "100_000".  Please send me your
opinions, etc.

I would be particularly grateful if people could point me to Ada
source archives so I can make some simple statistical analysis of real
code, or if you would like to "grep" your own code and let me know
what you got.

The reason is that the C++ standardization committees have received a
proposal to allow "_" in numeric literals.  We are interested in some
sort of indication if people find this feature useful, and if it is
commonly used in languages that have it.  If nobody uses "_" there is
no reason to add it to C++, and if it provides a significant
improvement in readability, C++ could use all the help it can get :-)
