You're absolutely right, thanks!  Documentation fixed in 8d50158 which will be 
in the next release.

hook before_template sub {...} is of course wrong, as there's no comma (fat or 
otherwise) between two params to hook() (and without the fat comma, 
'before_template' doesn't get auto-quoted, so it's an unknown bareword, too).

Hopefully I'll get a chance to dig further after $work; so far, I've not been 
able to reproduce the issue you're having.  I think the machine I tested on is 
still on 1.3050, though, so it may be something that changed in 1.3051.  I'll 
try 1.3051 and/or devel and see what happens.
