Variables within variables.

Hi all.

What I want, in perl, would look like this.

$tal->{onething}->{ $tal->{otherthing} }

I tried

string:stuff${onething/${otherthing}}

but it didn't work.

Is this supported, or should I work around?

Thanks in advance.

I still have a suspiction that a SAX parser with heavy use of
memoization would be faster, but it's no trouble for me now.

I'm even getting close to being able to show off a primitive version of
the site I'm building.  I'll mention it here when appropriate.

Re: Variables within variables.

I was just fixing some (really stupid) mistakes in the Petal 
QUICKSTART pod documentation and found the answer to this question.

The Petal docs say this:

       You cannot write nested expressions such as:

          ${my_var/hello_world ${my_var/current_user}}

       This will NOT work. At least, not yet.

So I guess that means you can't :-P
