What's behind this ?

Actually, we get the "template" variable available in the TALES namespace.
"template", when used in a macro, refers to the template that uses the
macro, and not to the template that contains the macro.


IMHO the underlying problem is that there's no clean way to control the variables used in a macro. Macros inherit whatever variables the template happens to be using. You can usually predict what variables will be available, but you have no guarantees. You might not even get "template" or "here".


We recently had a discussion about this:

The conclusion we came to is that we need a new kind of construct, tentatively called a "subtemplate". Subtemplates accept parameters and have full control over the variable namespace, including the "template" variable.
