Example: PACKAGE_native_append += "something". "append" is a keyword, but the "native" is just a separate list of native packages, yet both are appended to a variable name separating it by underscores. They use the same "syntax". If my memory serves me correctly, if not in this example "+=" is required sometimes after "append", even if they seem redundant. Someone politely explains you why this works as it does, it makes sense, yet you wonder why you need to hit a gotcha when all you are doing is something as simple as adding an item to a list (as a space separated string).

And then the metadata is also funny, e.g. do_patch[depends] = "whatever:do_populate...". Variables are not just variables, they can contain metadata, sometimes important.

It feels like there are usage patterns, good practices and something more beautiful wanting to get out, but this is a domain where making a better build tool would break tons of recipes, so it feels like everytime they got a problem they added a quickfix and got forward without looking back.

The steep learning curve most of the time is unneeded, you are frenquently doing trivial to simple taks and hit one problem that gets you blocked for a while for things that you are easily able to do outside Yocto.

It is a shame that the good work they do is spoiled by the horrible "interface".
