Hmm.  Currently Dancer proceses the view and the layout separately; from a 
brief glimpse at docs on TT's wrapper directive, it looks like it may work for 
us:

http://template-toolkit.org/docs/manual/Directives.html#section_WRAPPER

When I have a moment, I'll have a crack at making it work.

Since ideally we wouldn't want to change behaviour by forcing the user to add 
a [% WRAPPER %] around their views, I think we'd need to read the view 
ourselves, add the [% WRAPPER %] stuff to make use of the selected layout (if 
there is one), then pass the modified view to TT to render; seeing the 
wrapper, it should automatically wrap the layout template around the view 
appropriately, I think.

Thanks for bringing this up; it would indeed be nice for things declared in 
the view to be accessible in the layout!

Cheers
