Hm. I need to keep track of the order of the equations.
If I have two expressions (terms?) and an equation expr1 ~ expr2, I can extract the Left Hand Side and the Right Hand Side by
@variables expr1 expr2
(exrp1 ~ expr2).lhs
(expr1 ~ expr2).rhs
Is there a function to do the same, or should I use comprehension if I want to do this for a vector of equations?
