I will try to take a look at this later.

In GlobalEnv there is:

    /// this is a map of keywords, which trigger syntax extensions
    public SyntaxKeywords : Map [string, GrammarElement];

    /// this is a set of keywords present in current global environment
    public Keywords : Set [string];

GlobalEnv are created in PreParser basing on 'using NameSpace;' and
'namespace My { ... }' declarations.

The example of using GrammarElement is in
ncc/parsing/MainParser-Extensions.n, in particular there is

parse_top_extensions (modifiers : Modifiers, target : MacroTargets) : void

and

 parse_grammar_rule (tree : GrammarElement, stop : TokenStoppers,
target : MacroTargets)  : GrammarElement * list [SyntaxElement]
