almost every concept in computing is about one or more levels of
indirection.

yes, but that's not saying much - almost every language in existence
provides a cleaner and smaller alternative to c++.

i guess that's why the language spec alone is a svelte 500 pages.

not meant to learn?  do javadocs have an ESP mechanism built into them?

no it isn't.  it's nowhere near as easy and natural as the limbo, alef,
erlang etc. model for concurrent programming.  otoh, once you get used
to it, everything looks easy and straightforward.
