Comment (by ncohen):

 > One technical problem is that matrices in Sage can always be multiplied,
 so you can't create matrices over linear functions.

 I don't understand `O_o`

 We do not mind if two matrices are multiplied, we mind when two LP
 variables are multiplied together. We just have to scream when two
 variables are multiplied, don't we ? So if a guy multiplies two matrices
 containing variables it will try to multiply the variables at some point
 so we are safe, aren't we ?
