Pushed to -3-5 now as 
(needed some trivial adaptation to -3-5, and I had not been aware you 
had already pushed it to master, so it lacks a cherry-picked-from in the 

* I would probably also have moved the <...>* syntax down into stoc; 
this would have made the case detection in SimpleRegistry::open more 
straightforward, and would have lead to a less broken 
SimpleRegistry::getURL.  (Also, it is not clear to me what your "FIXME: 
busts the 'create' mode ..." wants to imply, as creating old-style 
binary rdbs should continue to work just fine, right?)

* err_throw is gone to from only one place, so could be simplified.  And 
if it were gone to from multiple places, I would consider that 
unfortunate, as, for debugging purposes, a throw expression carries 
additional information via its textual location in the source, which is 
lost if multiple error locations go to a single throw statement.

Anyway, I did not clean up any further as I plan to broadly modify this 
area, anyway (reducing the "nesting nonsense" to zero, independently for 
services and types).
