Hi Graeme
Based on the code snippets you provide, it's not clear (at least to me) what
you want to achieve. Is it possible that you post the module?

If the hash is assigned to $self or not does not matter, it is in both case a
non object data structure.
And designing the content of %conf below as an object with a method
get_users_table_and_columns() returning all object attributes makes, I think,
not much sense.

This seems to be an object method, $self being the object.
Do you have a new() class method in your module?

Since this %conf has fixed content, you could set all that during object
creation ( new() ) and store it as object attribute, like
$self->{conf}={table=>'blog',...};
> return %conf;
...and the method (hopefully not the only one in the class) would get shorter:
sub get_users_table_and_columns{
return $_[0]->{conf};
}
It returns a hashref instead of a hash.
