1# Let's have some fun -- try to match a C comment.
2# first the obvious, which looks okay at first glance...

5/\*.*\*/  -         /*x*/y/*z*/         /*x*/y/*z*/
6# okay, we must not match */ inside; try to do that...
7/\*([^*]|\*[^/])*\*/          -         /*x*/     /*x*/
8/\*([^*]|\*[^/])*\*/          -         /*x*/y/*z*/         /*x*/

10/\*([^*]|\*[^/])*\*/          -         /*x**/y/*z*/        /*x**/y/*z*/
11# and a still fancier version, which does it right (I think)...
