According to the spec, the signature of opApply must be "int opApply(int 
delegate(inout Type [, ...]) dg);", so it's actually a bug in your code 
that the delegate's parameter it isn't marked inout.

(unless of course you prefer to consider it a 'bug' in the spec that 
it's not allowed to be marked 'in' :) )
