I suspected there must have been a very good reason for this not 
being possible at compile time and this definitely looks like 
one: thanks Vladimir for tracking this discussion and clarifying 
it to me!
So I guess this answers all my questions and. as a beginner, I 
can also say I learned something in the process: thank you again!
