  Well, the discussion was about using keywords as variable names, like:

	if if == then then then = else else else = end end

  But there are still issues, like not all of Unicode code points are valid
alphabetic characters---you have a block of mathematical operator
characters, digit characters for different languages, combining characters
which now include colors.  The rules get rather complex rather quickly ...
