No more macros

If a problem involves a lot of formulae that are identical except that they each apply to a different point in time, MM allows one to write just one formula for this: profit[t] = income[t] - outgoing[t]. Conventional spreadsheet development requires a separate formula in each cell, either written by hand or generated by a macro or Visual Basic program. Writing multiple formulae by hand increases the chance of errors. Using a program to generate them makes the model less readable, since you need to read not the model itself, but a program that generates it.
