Tavis and I have talked about starting to try to phase out the "#include"
statement so I wouldn't exactly recommend it if you can avoid it.

What it sounds like you need is an addition to Cheetah I just released,
proper @staticmethod and @classmethod support. Basically with
@staticmethod support you would have syntax like this:


dir1/dir2/dir3/foo.tmpl
=================================
#@staticmethod
#def FooFunct($param1, $param2):
   #return ($param1, $param2)
#end def


dir1/base.tmpl
=================================
#from dir1.dir2.dir3 import foo

$foo.FooFunct('omg', 'rly?')



The import and calling syntaxes mirror that of Python static methods
themselves in this case as well.

You can find @staticmethod and @classmethod support in v2.1.2 which I'm
preparing for release today (it's already been tagged)

If you really *must* avoid first compiling foo.tmpl, then for now the
#include would be what you'd want. See:
