Currently the get and find members only take std::string :

SEXP find( const std::string& name) const ;
SEXP get(const std::string& name) const ;

What they do with the string is that they first make a symbol, with install and then they call the relevant C/R API function, i.e. Rf_findVarInFrame or Rf_findVar.

But sometimes, we already have a symbol and perhaps don't want to pay for the double cost of:

• converting that symbol to a std::string
• let get or find reconvert it to a symbol

The alternative being calling C/R API directly.

So can we have:

SEXP find( Symbol name) const ;
SEXP get( Symbol name) const ;

This is straightforward, and I'll probably submit a PR anyway, but since I don't have time right now, I'm just logging the need and intent here.
