[SVN] REQUEST: Scope Querying API

[Alain O'Dea]

I would like to be able to query the current file or other project  
files for symbols based on scope. I would also like to be able to  
query for symbols with a common instance of a parent scope.

For illustrative purposes I will use JavaScript-like syntax and JS DOM- 
like API:

// get all atoms in the current document
document.getSymbolsByScope("source.erlang meta.function.erlang  
meta.structure.tuple.erlang constant.other.symbol.unquoted.erlang");

// get all atoms in the current function
currentFunction = currentScope.getAncestorByScope("source.erlang  
meta.function.erlang");
currentFunction.getSymbolsByScope("source.erlang meta.function.erlang  
meta.structure.tuple.erlang constant.other.symbol.unquoted.erlang");

// get all functions in the current module
document.getSymbolsByScope("source.erlang meta.function");

Is similar functionality already exposed to Bundles and Plug-ins? If  
so, how do I use it?
