That seems nice. A simple scheme would be simply a function call
like   compatmode5_0() or something like that.

Should it control the "whole" compatibility at once or should it
control different issues independently?
(e.g., compatmode5_0("longstrings") would set compatibility only
for long strings/comments...)
