Thanks for posting that.  Reading over the code I'm reminded that 
I never cared whether something was an rvalue or lvalue before 
writing D code.

It's off topic, but I forget why managing memory for rvalues* was 
pushed onto the programmer and not handled by the compiler.  I'm 
sure there is a good reason but it does seem like a symmetry 
breaking requirement.

*or was it lvalues, I can never keep the two separate.  Wish the 
some other terminology was adopted long ago, such as "named" vs. 
"ephemeral".
