[asdf-devel] Cache? Translations? How to get rid of them?

[james anderson]

good afternoon;

this does not sound like a case for specialization. it sounds more  
like delegation.
what about hooking an output translator into the components.
if it is there, it is used. if it is not, no translation happens.
(as much as i may regret this) the "standard" output translation is  
supplied as the default initform / or default initarg.
if one supplied nil in the initialization form, that is used instead  
and no translation happens.
