re: RFE #468 (http://sourceforge.net/p/oorexx/feature-requests/468/)
Attached patch implements ~left and ~right methods that not only return the data
but also edit the mutable buffer in place.
The patch was made against trunk, svn revision 8278.
I compiled on openSUSE 11.4 (Linux 188.8.131.52-0.20-desktop x86_64) and made
a few manual tests in ooRexxTry.
It would be nice if you could indicate whether you object to the edit-in-place
feature before I make the test groups.
