[Zope] Name lookup emulation with a Product

[Pierre-Julien Grizel]

Hi,


I'd like to perform a name lookup inside a product, relying on
acquisition, property and REQUEST lookups.

In fact, I want to use the DTML Reference / Table 7 schema to look-up
variables.


I know how to perform REQUEST lookups.
I know how to perform object properties lookups.
I know how to perform acquisition lookups.

I could write a method of my own to try to imitate the Zope process, but
is there an already existing method (that would be used by the dtml-var
source code, for example), that already does the job for me ?

I found the BaseRequest / traverse method that seems to do it, but is
there a convinient way to call it ?


Many thanks,




Pierre-Julien
