Hi,
Can someone help me figure out how to do nested variable resolves and evaluation of numeric operations?
I am trying to make a system that stores formulas and variable values in an external file, and i want my perl script to pull in the values and the formulas, and then evaluate the formula with the variables having their values substituted into the formula. A small, representative, and problematic piece of code follows:

`my $x = 3;
my $y = "2 * $x";
my $z = eval {$y};
print '$z is: ', $z, "\n";
print 'eval of $z is: ', eval{$z}, "\n";
print 'eval of "2 * 3" is: ', eval '2 * 3', "\n";
`

What I want is for the 2nd print statement to evaluate to the value '6', which the 3rd print statement does. Below is what I get:

$z is: 2 * 3

eval of $z is: 2 * 3

eval of "2 * 3" is: 6

Again, can someone help me figure out how to do nested variable resolves and evaluation of numeric operations?
Thanks,
Matt
