Research direction
Start with the cpp11::sexp API and the original discussion in pull request 209. Determine how the requested inspect() accessor should represent SEXP values and how the optional depth limit should behave. Done means both example calls return usable debug strings with bounded inspection for the depth overload.
Written by the indexing model from the issue text.
Description
It'd be helpful for error messages, logging, and other debugging to have easy access to a string representations for SEXPs in C++. This could return the equivalent of .Internal(inspect(some_sexp)) or capture.output(print(some_sexp)).
See original discussion here: https://github.com/r-lib/cpp11/pull/209#discussion_r674209915
cpp11::sexp value = ...
std::string str = value.inspect();
std::string str = value.inspect(/*depth=*/2); // limit inspection of sub objects
