next steps for the new parser/grammar

 - acyclic vs prunable; introduce GC hints
 - CGEN: ``restrict`` pragma + backend support; computed goto support
 - document NimMain and check whether it works for threading
+- parser/grammar: enforce 'simpleExpr' more often --> doesn't work; tkProc is
+    part of primary!
+  * check that of branches can only receive even simpler expressions, don't
+    allow of (var x = 23; nkIdent)
+  * document the new grammar: ^+  ^* operators; indentation handling
+  * remove rules in the manual as it's too hard to keep it up to date
+  * improve rules to contain the AST structure
+  * the typeDesc/expr unification is weird and only necessary because of
+    the ambiguous a[T] construct: It would be easy to support a[expr] for
+    generics but require a[.typeDesc] if that's required; this would also
+    allow [.ref T.](x) for a more general type conversion construct; for
+    templates that would work too: T([.ref int])
