I'd strongly advise heeding the above advice to avoid using a variable as a variable name, but eval might get you the hack you're looking for: 
  my @MyArray = ( 1, 2, 3, 4 );
  my $varname = 'MyArray';
  my $x = eval '$' . $varname . '[0]';  # THIS IS BAD!!!!!
  print $x; # 1

Update: I should re-emphasize that the above is BAD as in "don't cross the streams" -- I only posted it because it technically works and the OP insisted on knowing any kind of way to accomplish it.
