How so? In what scenario would you ever need to use a sequence like <tab><space><tab> in indentation in your source code? Let alone using esoteric Unicode whitespace characters for indentation. I think it is perfectly reasonable for the language to make the restriction that indentation must be either all tabs, tabs followed by spaces, or all spaces.
