What about [[ http://www.swig.org/Doc1.3/Arguments.html#Arguments_nn5 | this ]] 
?

The article speaks about pointer arguments, but in my (simple) test, it seemed 
to work fine for references as well...

The original progress patch (D97739) has a test running on linux, so I'd expect 
this should work there too. The test in that patch is disabled on windows, but 
that might be due to some vscode issues. I don't see why there should be any 
differences between windows and linux in terms of the dwarf events generated -- 
both of them don't use accelerator tables by default.
