Not really, but it is the only "clean" way if you want it all in a
single function.

The current solution is rather uncommon and confusing. As it checks for
an atomic first argument,

   (<xml> *Sock ...)

would work, while

   (<xml> (: sock) ...)

would not. This is hard to remember and document. Besides this, the code
duplication at the end is not really elegant ;-)

One way would be to write two separate functions.

Another way (and the one I would prefer here) is just to reserve only
'T' as a special case for a first argument. Wouldn't this be easier
(i.e. no 'out' at all)?

Then (<xml> T ...) would generate a list, while (<xml> ...) would write
to the current stream, no matter if it is chunked or not.

This is true. If you nest an 'out' within a 'ht:Out', the inner 'out'
takes precedence and causes normal, non-chunked output.
