[OT] compiler optimisations

[Lucas via Digitalmars-d]

I think Andrei has some good ideas and I like seeing his and 
others perspectives. Everyone has different experiences and can 
bring something to the table, which can cause some interesting 
disagreements, but more viewpoints add perspective. The 
difficulty is that everyone has their own agenda of why they want 
their change, and value is different depending on what kind of 
work you do and what domains your familiar with.

I actually do like that D2 wasn't afraid to break things. I 
actually like breaking changes if done for good reason, but I 
can't say I know all the changes in D2.
