My apologies, I didn't read your post all the way down to where you
proposed a language feature.  I suggest that you make that clear near
the top of the message and/or in the subject line.

My (slightly more considered) feedback on this proposal is that we're
unlikely to add a language feature *specifically* for progress
reporting.  Rather, we'd like to have language features that allow users
to build features like this one as libraries.  Some kind of (hygienic)
macro system comes to mind.
