Some ideas about order sensitive features:

In builtin.jam some features are commented as 'order-sensitive'. Looks
like there was an attempt to implement them?

I have an idea how they can be implemented. We already have "&&" syntax
and the only problem is that several features may be passed from
different places. Once a feature is added to a property set the last is
re-sorted. I guess this can be changed for 'order-sensitive' features so
that each new passed value will be attached to the only feature in the
property set. All values of a feature will be concatenated with "&&"
into a single value. Order will be preserved.

I think it will work and order of values will be deterministic. What do
you guys think?

Best regards/Venlig hilsen,
