Properties will be coded a lot in Scheme. So the interface needs to map

Well, the C++ and Scheme interfaces can feel different and idiomatic

Well, I find it better if it doesn't require reworking the control

My personal take on this would move the magic out of the normal reach of
users. You get (*start-column*) and (*end-column*) which you can use
for accessing the respective fluids but the function *start-column* does
not merely access %start-column

My criterion is rather convenience. scm_c_with_fluid could
be convenient if I could use it with a lambda. However, I cannot,
I'd need to define a separate function every time,
I wonder if you can 'chain' them:
Dynwind_context dwc2(dwc);
(you can at a minimum 'pause' dwc so to emit a runtime message that the
"wrong" thing is happening, but I guess you could hand yourself to your
parent and do more sophisticated shenanigans too... I must say I loathe
this stateful stuff

The existing code in fluid.hh is concerned with retrieving
fluids. I'm asking about setting them. Whether the new code
can go in fluid.hh is a question, but

Hi Luca,
Thanks for your insights! Much appreciated.

I'd think you can up this by one, and get a cleaner looking piece of
code if you implement scm_dynwind_fluid() as a forwarded method on
