I am confused by the placement of REBOL on the Y coordinate. If REBOL
is "more efficient" than TCL or Visual BASIC would not greater
efficiency place it lower on the Y axis, say between Visual BASIC and
C/C++/Java? Would not placing it higher than Tcl imply it takes more of
the system to do the same thing rather than less?
