Please don't take this as “ask fewer questions”. I only meant that  
your research should include studying examples of E as written in  
practice.

The existant such reference is <http://www.erights.org/elang/grammar/index.html

Note that in E-on-Java, E source is always parsed into Kernel-E; there  
is no full-E AST except as implicitly defined by the EBuilder (or is  
it ENode. In E-on-CL, there are “nonkernel” AST node types. Future  
plans include migrating to the latter approach, because it enables  
code transformation applications where the result should be human- 
readable (prettyprinting, refactoring, etc.), and because the  
introduction of concretely-named temporaries interferes with e`` AST  
manipulations.
