```
+#### %timing
+
+Prints out timing information from the last stellar statement executed.
The information has the total
+execution time, and also a break down of execution time by stellar
function.
+
+%timing supports filter on the timing output. If you pass one or more
strings to %timing, only
+execution times those each of those tags will show. Any functions that do
not have ALL the tags passed will not display

> It would be nice if stellar processor(s) could optionally instrument function
> calls to test performance.
> The result would be some structure with the calls, the times and maybe some
> context as a list or map
