The most logical I could come with is:
"g_expressions"(the calculator) is a tool, hence it should be instantiated by spreadsheet.g_Formula_cells, which is the main program/library.
The spreadsheet is the main library so its generic Spreadsheet.g_formula_ cells shall be provided a g_numeric_signature, which it will use to instantiate g_expressions.
The problem, is that the son of g_expressions, call it B, depends on "spreadsheets" to define a new syntax including spreadsheet coordinates.
And like I said I can "limited with" nothing, since all packages are generics.

I hope the explanation was clear. What would you come up with ?
