Now this is funny, after implementing that optimization 
(https://github.com/jll63/methods.d/blob/94ad5a945b3c719bd8f8402bb0aa6fda8e7a6be0/source/openmethods.d#L388, https://github.com/jll63/methods.d/blob/94ad5a945b3c719bd8f8402bb0aa6fda8e7a6be0/benchmarks/source/benchmarks.d#L139) it runs faster with ldc2 but slower with dmd. I may be testing the limits of dmd's willingness to inline my mess ;-)
