I don't entirely subscribe to the (1) one, it seems to be mostly a shorthand
argument.

But (2) is somewhat logical and interesting. an. funcs allow to wrap a call
to a procedure together with its arguments inside a anonymous function
(closure-like) and queue that in a different thread and have it executed
there by RTL code.

I think that (2) is the main reason for anonymous functions, and people
shouldn't assume that the use of an. funcs is the same as in functional
languages. (IOW for expressions)
