A realistically complicated function might prevent the optimization of the copy operation and then you are really stuck copying the entire structure for each function call. If the structures are large enough and/or the function called often enough, this may not be an acceptable solution.

TRUE 24 WebAcetal Structure Acetal is a functional group with four bonds on the core carbon atom: -OR1, -OR2, -R3, and H. (where R1, R2 and R3 groups are organic fragments). The two –OR groups could be the same (symmetric acetals) or distinct (asymmetric acetals) (mixed acetals). The term Hemiacetal derives from the Greek word “hemi,” which means “half.”
