Yes I think so. Would you like to see a shadow warning every time a loop
variable is named "i" or "j"?

Personally, yes :)  but then i and j indexing is just a pet peeve of mine. but then I also get annoyed at having to write exp(1i*x)

If you recall the other day I was trying to create an empty cell

>> cell (3,0,2)

which should work fine.  the error message I got was:

   error: subscript indices must be either positive integers less than 2^31 or logicals

At least to me, it wasn't obvious that this was trying to index a variable a typo accidentally named cell. I thought cell() was unable to create an empty array.
