Well, they're going to have to change somehow, because the concepts of "left" and "right" are going away (see #20303).  However, your suggested new name for these functions would be awful for large groups.  Consider curses.window.overlay:

window.overlay(destwin[, sminrow, smincol, dminrow, dmincol, dmaxrow, dmaxcol])

Your algorithm would generate the name "use_destwin_sminrow_smincol_dminrow_dmincol_dmaxrow_dmaxcol".


I suggest instead: remap the names to less-confusing names in your
impl function.  Compiler optimization will make the redundant name disappear, so it will have no run-time cost.
