Substitution should just substitute, not optimise
This was causing Trac #4524, by optimising
(e |> co) to e
on the LHS of a rule. Result, the template variable
'co' wasn't bound any more.
Now that substition doesn't optimise, it seems sensible to call
simpleOptExpr rather than substExpr when substituting in the
RHS of rules. Not a big deal either way.
