The toybox version does not yet take this into account. For example
find . -type d -o -type d -a -type f
should print something. This third point doesn't seem
straightforward to implement to me.
No, but adding a test to a scripts/test/find.test would be. :)
(Yes, I regret "scripts/test disagreeing on plural/singular. I'm
pondering moving tests up to the top level directory, actually...)
(Summarizingly the way how find evaluates composite expressions is
strongly inspired by how the C language does.)
I still have to implement bc and make $((blah)) work in toysh. (I
actually wrote a math expression parser in Java of all things, back
in 1998. The principle's fairly straightforward...)
