Your file didn't make it through the mailing list (which is quite
restrictive about which types/extensions it will take).
I appreciate your enthusiasm and persistence for this issue, but I
suspect you may have trouble convincing R-core to adopt your changes --
they are "better", "easier", "more intuitive" for you ... but how sure
are you they are completely backward compatible, have no performance
issues, will not break in unusual cases ... ?
Hopefully someone here will set up a bugzilla account so you can post
your patch/it can be further discussed there, if you want to purseu this ...
cheers
