Grr. Of course this works. sigh. I think I spent too much time looking at the first page of the TT perldoc where it tells me to pass it as a reference. I tried every combination of \&some_sub I could think of... elbieelbieelbie	[reply]

You only need to pass the sub as a reference if you plan to call it from within the template. Passing it as a ref lets you do this in your template: `[% filler(some_var) %]` [download] Personally, I like to avoid callbacks from within templates when possible, but this can be useful for things like passing in a subroutine that escapes HTML characters.
