With symbolic refs you are using a hash -- it;s just hidden in the internals.
Anyway the lexical names are not entirely thrown out by the compiler, and
there is a way to do symbolic refs against lexicals -- it's eval-string
my $database_name = 'cheese';
my $variable_name = 'database_name';
print eval "\$$variable_name"
