I need the same feature, but I don't really see an efficient way to do this 
in the language itself.  It is probably better relegated to a template. 
Also, rather than giving all threads access, I would limit access to each 
"thread-local" variable to a thread pool of constant size.  In other words, 
only threads in a particular thread pool could access this variable.  This 
way, the variable can be represented as an array that never needs resizing, 
where each thread in the pool has an index to an element in the array.
