This syntax doesn't solve the original problem of course.

People have requested -= and I've been wondering if we should add that
as a search and remove operator. To match the existing language that
would have to work on space delimited lists though so its of no use to
this use case. We could pair this with a *= or operator which worked the
same way without the space delimiter like .= does...

S *= "-native"

?

maybe ~= would be a better pairing with -=?

Having syntax which allowed variable reuse like the original example
above could also be useful:

S = "foo"
S *= "${S}-native"
print bb.data.getVar("S", d, 1)
    foo-native

Does anyone have any other language enhancement requests for bitbake
while I'm thinking about it (or any thoughts on the above)?

Cheers,

Richard
