You know, I think you might have nailed it. Intuitively that seems correct.

I did it this way to divide the parsing of the input file from the format of the output. So the backend would say "I've found a glark element", and frontend A may say "Ignore it", while frontend B may say "Concatenate it with the preceding output".

The plan was for the client to say:

my $obj = Backend->new(frontend=>FrontendClass);

But, as you point out, far more sensible is for them to say:

my $obj = Frontend->new;

Then to have Frontend use Backend. :-) Thank you very much!
