That might help, but protecting things is a fairly cheap operation, so I
don't know if people would bother with the naming convention. It's just
as easy to just protect things if you're not sure.
One way things can go wrong is when you think you protected something,
but then the pointer chang

For a long-term horizon, would it help R developers to use a naming
convention?
Perhaps, varName_PROT, or the inverse varName_UNPROT?
Eventually, teach some linter about that?

Oh, with the abuse of 'warn' in my previous message, warning would be issued
if the input 'v' of 'coerceToString' is a logical vector of length 1.
Revision:
Added to my changed 'StringFromLogical':
if (*warn) {TrueCh = FalseCh = NULL; *warn = 0;}
'coerceToString': insert
if (i == 0) warn = 1;
On second thought, I wonder if the caching in my changed 'StringFromLogical'
in my previous message is safe. While 'ans' in the C function 'coerceToString'
is protected, its element is also protected. If the object corresponding to
'ans' is then no longer protected, is it possible for the cache
