I have a use case that requires  repeating performance measurements of blocks of code that do not coincide with function start and stop.  For example, a function will be calling several sub-operations, and I  need to measure the execution from the call statement until the execution of the statement following the call.

So, ideally, I'd like to mark the start and stop points in the source code with label pairs, and have these exported as symbol/address pairs.

I would read these label names with an external app, and would set up the performance measurement start and stop window boundaries without modifying the target code.

Does D provide any feature that would allow me to export such labels?  I've seen some discussion of use of goto labels within the program, but nothing about exporting them for use by an external app.  I've also read through the recent info on user annotations, but those seem to be associated with data properties and it isn't apparent to me if they could provide program address info.

Thanks,
Jay
