Along these lines, can someone explain to me why
  use strict 'vars';
  my $name = 'data';
  print foreach  @$name;

produces no error, when

  use strict 'vars';
  print foreach  @data;

does?

Because in the first case, the variable you use had been declared, and 
you hadn't enabled strict 'refs'.
