To help LDC/GDC

[bearophile]

I remember Walter saying two or more times that the semantics of 
D offers some optimization opportunities that probably are not 
yet used to try to reduce the run-time of D programs. Is Walter 
willing to write down a list of such opportunities? (Ideas from 
other persons are welcome). Maybe some LDC/GDC developer will 
make the GCC/LLVM back-ends use them. The implementation of those 
ideas will require some time, so later it's better to put the 
list in the D wiki.
