"To instrument" means "to measure", but to me at least with a connotation of having points where to hook things to.

I didn't even recognize the original comment as mine, and I'm not really sure what I meant back then. I guess that my reply stemmed from a reading of perl510delta or the changelog of the profiler.

But yes, I think I suggested back then that the extra granularity/detail resulted in attributing 17 ms to a BEGIN call that was not separately accounted for in 5.8.8. I guess the time spent in the BEGIN block was added to the time spent in the main program.

    Thanks!

    (my first association for "instrumenting" is to provide a bunch of kindergarten kids with vuvuzelas... ;)

      My first reference to "instrumenting" was when "they" hooked the bus/tag cables of a 3490 to a hidden port on a 390-class engine on a lab box and captured the psw on the fly, filled up a tape REAL FAST too.

      I had heard "instrumentation" as a word before (in the sense of adding measuring points/code to a program), but being a non-native speaker, I'd expect the corresponding verb being more something like "instrumentate" :-)
