Hi,
In Java/C# you can create purely static classes.
These are classes whose methods are all static, the classes
cannot be derived from or instantiated:

static class Algo {

Yes, I actually want to replace a SAX parser.

I wanted to do some quick benchmarking to figure out what works.
When I run this:

auto sw = StopWatch();
sw.stop();
I need a case-insensitive check to see if a string contains
another string for a "quick filter" feature. It should
preferrably be perceived as instant by the user, and needs to
check a few thousand strings in typical cases. Is a regex the
best option, or what would you suggest?
