draft proposal for ref counting in D

Walter Bright:

Where are the benchmarks that show that this is a good idea in 
some real situations? This is the essential first step.

What if a programmer adds only one of those two? Currently if you 
add only part of the hashing protocol (or you bork a function 
signature) the compiler often gives no errors.

What are the plans for coalescing and optimizing away some 
reference counts updates?
