This would also increase readability.

That's problematic if there's more than one variable. 2*x*y can't be displayed as 2xy, because 'xy' is ambiguous (is it x*y or is it a variable called 'xy'?). 2x*y? Yuck.

I intentionally omitted that one because it's the "bullet" character [•], too big for a multiplication symbol. 25CF [●], the "black circle" character, would be even more annoying. IMHO.
