I'd be quite keen to avoid such things.
Nowwhere else in Perl do we do this sort of handling of code dispatch
based on argument types (except for normal dynamic virtual method
dispatch). One thing I've always liked about Try::Tiny et.al. is that
they don't get involved in working out how 'catch' dispatch should work.
We our core 'catch' to have to make such decisions, it suggests a
slippery slope:
Do we start adding similar logic in other places? Multimethods?
Does it just use class names? Can we put custom logic in - where{} clauses?
