I tried sending this once before, but I'm not sure it made it. Email
from the jakarta mailing lists seems spotty lately. In any case, I sent
it to the wrong mailing list in the first place (user, not dev). Sorry
in advance if this was already received.

Here is a little patch that makes note of the range operator in the VTL
guide in the #set and #foreach sections. In addition, an "Examples"
paragraph was added to the #foreach section (which seems appropriate
given the format of the rest of the document).
Thanks,
Pete
