i may be lacking the necessary bird's eye view here... but why not just use good old copy-pasted diff for this?
introducing extra complexity in the form of a new DSL has all kinds of costs that people usually ignore (*), and it's not clear to me how those costs would pay off compared to just copy-pasting a small diff into the package declaration. * lack of tooling; more opportunity for bugs; the ((line 10) (+ ...)) DSL is more fragile to upstream changes, etc) sure, diff would be more verbose and arguably less aesthetic, but it's much easier on the brain of the coders, and is less fragile, too. and larger patches could go through the current, convoluted local.mk way. - attila PGP: 5D5F 45C7 DFCD 0A39
