Comment (by Mike Cowperthwaite <michael.cowperthwaite@…>):

 1) fmhess's 'advice' at that other bug looks like knee-jerk Microsoft-
 blaming, altho he might technically be right that these warnings are
 spurious.  (a) As noted in the original report here, several Boost
 libraries have already taken steps to prevent them. (b) A spurious warning
 here might be a non-spurious warning elsewhere; and this warning cannot be
 suppressed using MS's `#pragma warning`.

 2) Not sure which "problem solution above" you're referring to: there is
 code in comment 2, and code in the original report.  The code in the
 original report is similar to the solutions I found in other Boost
 libraries.  The code in comment 2 looks like it might work fine; whether
 copying a `UnaryFunction` object with every instance of `output_proxy`
 would be undesirable overhead, I cannot say.

 I'm curious to know if Paul Saville's `assert()` has ever been triggered.
 (Also, Paul correctly pinned the cause on the "reference member variable,"
 not a "const data member" as I originally stated.)
