This situation arose in a computer practical this morning. A student overwrote "c" with a function. This messes up lots of things, but it is difficult to remove the function "c" from the global environment because it is used as a function in both "rm" and "remove". [The solution was to reassign "c" as a number, and then remove it.] Would it be reasonable in "rm" and "remove" to insist that the "c" function is got from the base? The same might apply to ".Internal" and "as.character", which are also used.
One thing we've been talking about a bit is adding some form of name space management. This would insure the the c referred to in rm would be the c in base. luke
