R feature request: stop(..) should print its caller call

The following shows what I mean:
tst<-function(x)in.tst(x); in.tst<-function(y)stop(paste("y is",y)); tst(pi)
in R gives
-------------------- Error: y is 3.141593 --------------------
in S-plus gives
----------------------------------------
Error in in.tst(x): y is 3.14159265358979
Dumped ^^^^^^^^^^^^ ----------------------------------------
For locating bugs / problems in functions, it would be tremendously helpful if R also printed the name of the function from which it is called (actually the ``call(..)'' rather than just the function name).
Martin, I am not sure. I find it more useful to call traceback() after an error occurred to find out what really happened. -k -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
