A variable of which the name is stored in another variable 1

[serpento]

If I have the name of a variable stored in another variable, can I read the contents of the variable? EG:

  $nameOfVariable = "foo";
  $foo = "contents of variable that I want to read";
  # Now, supposing that $foo could be anything,
  # eg. $sweetcorn, is it possible to read the contents
  # of the variable using $nameOfVariable?

Any help would be much appreciated!

#!usr/bin/perl
print "start\n";
$nameOfVariable="foo";
$foo="contents to be read";
$tmp="\$$nameOfVariable";
print eval("$tmp")."\n";
print "finished\n";

There's probably an easier way
