I believe, this is an idealistic approach. MS compiler is not affected by source-code transformations, gcc generates better code after transformation and I believe dmd is not so advanced as gcc, but language itself gives some syntactic aid to optimiser.

Short-circuit evaluation is influenced from code. As well as array notation.
