What do those rules say about code like:

    int hi = 5;
    int שָׁלוֹם = hi;
    int hello = 10;
    int السّلامعليك = hello;
    myfun(שָׁלוֹם ,السّلامعليكم)

IMO this code is fundamentally valid: we should allow
programmers to write identifiers in their native tongue.

Does the security guidelines require override chars to force the
`, ` to be in LTR, so as to fix the ordering problem (and would the
result be more or less clear to someone familiar with those RTL
scripts ;-0 )?
