Well, I'm starting to get a feel for C again. I had forgotten the joy of hand-crafting pointer loops to do any kind of string manipulation.
That's irony, of course. But it is neat to run my 500 line C program in a debugger and to be able to step through it statement by statement.
On the other hand, I have almost never needed to use a debugger on my 250,000 loc distributed Java program.
