Does that have advantages of using a browser() line or two? I find
them indispensable.
The error=utils::recover option will invoke a browser at the time of an
error, so it's very helpful when you don't know where to put the
browser() calls.
You should also consider using trace(), which inserts temporary
browser() calls (or other code). The setBreakpoint() function
constructs a call to trace() using source file information and is often
an easier front end.
