This undocumented extension was deprecated (with a mandatory warning when 
it was used) in 3.0, released June 18, 2001, and removed in 3.4.0, 
released April 18, 2004.  How long would you expect undocumented 
extensions to be deprecated before being removed, if nearly three years 
isn't enough?  The normal period for most deprecations is a single release 
(e.g. deprecate in 3.3 and remove in 3.4), which allows about a year for 
people to see and fix the warnings, but undocumented extensions are 
subject to change and removal without deprecation period - indeed, removal 
by accident if someone didn't realise they were part of the extended 
language.  The ease of fixing - in this case, by adding a single semicolon 
- is a relevant factor in deprecation; we simply didn't happen to get 
round to removing this extension until 3.4 though removal in 3.1 would 
have been reasonable.
