> .ONESHELL ensures each Make recipe is ran as one single shell session, rather than one new shell per line. This both - in my opinion - is more intuitive, and it lets you do things like loops, variable assignments and so on in bash. This will at some point cause a bug that will be a pain to debug. Even worse when it depends on execution order/thread grouping with -j8. I would not consider introducing state is a good thing.
