The "LSST C++ Programming Style Guidelines" has been installed into

It is currently a virtual copy of the CARMA C++ Coding Standards;
it will be refined over the next week to reflect the LSST Data
Management C++ Coding Standards.
Recommendation 5-13:
5-13. Variables should be declared in the smallest scope possible.
conflicts with 5-14:
5-14. Only loop control statements must be included in the for()
construction.
5-14 prevents one from limiting the scope of "sum" (not a loop
control variable) with this construct:
for (int i = 0, int sum = 0; i < 100; i++)
Also, I find their code example:
for (i = 0; i < 100; i++)
sum += value[i];
to be dangerous. One should always use curly braces to delimit code
blocks, even if they contain one statement:
for (i = 0; i < 100; i++)
{
sum += value[i];
}
It improves readability. I've been burned more than once by the
other construct.
