The variable expansion is always done. If some value with $ is added to some variable, the next reading operation [1] causes variable expansion.
For example, set
$config->{ key } = '$ml_home_dir/value';
here.
The next read operation e.g.
$config->{ another_key }
(where the key is any) evaluates the variable expansion.%_fml_config hash holds pairs of key and value. The format is $dir/$file in this hash, it is not expanded. get() returns the value of %_fml_config_result. The value in this hash is after the variable expansion. The variable is expanded in calling get() method.
