Hi,
Is there a way to retrieve the parsed location of currently executed
function?
In other words, how to define a function foo such that when sourced
from a file file_with_foo.R containing foo() at line 1, it should

foo called in file_with_foo.R at line 1
Thanks,

I don't remember what rpartpl once did myself; as you point out it is a routine that is no

And just in case anyone is curious about the history, return() with
multiple arguments was legal in S2 but the syntax in the blue book had
only return(expr), whether enforced or not in the code.
