Well keywords starting with two underscore are reserved by the standard
for extensions like this :).
So having the keyword thread_local would be bad as it means it has to be
a context sensitive keyword.  Context sensitive keywords are much harder
to parse and you have to check to make sure the person actually used  
them
in the correct context and even then it becomes confusing.
Anyways __* keywords the correct way to have an extension anything  
else is
wrong.
