tree functions daily exercise: Table

The Perl version of the Tree function is posted. It's a bit long.
Please see the code here:
http://xahlee.org/tree/Table.html

the choice of having a string as the first argument to Table is a bit
awkward in Perl. Possibly i'll have to rewrite it so that the first
argument is a function instead, where in each iteration the the
variables are fed to the function. This necessarily breaks the
Mathematica's syntactical form of Table, and is slightly less flexible
in power, but is more natural and practical in non-symbolic languages
like Perl, Python, Java.

I think the goal of the whole tree functions project
http://xahlee.org/tree/tree.html
would make the code actually practically useful for processing trees in
each language, as opposed to sticking to uniformness of these functions
across languages.

later on, as we write more tree functions, the whole set will be very
useful in processing tree structures, such as XML and many other things
spurn from it today.
