After thinking about it a while I guessed that was going to be the case.

That's not going to work for passing the value around (to CGI.x or macro
calls etc) though - I'd need to assign it somewhere first before doing
that. And if I'm going to do that I may as well just do
[% SET val = mylist.size + 0 %]
with no need for an extra filter...
I guess there's not much I can do beyond wrapping that in a MACRO.
Thanks,
