&{$exception->{action}}(args); should do fine

Update You can also do 

local(*foo) = \&{$exception->{action}};
&foo(args);

if you want, temprarily globbing your subroutine ref to the name foo... either way works...

Update2 My bad, just realized I needed \ in front of &{$exception->{action}}; to make it work... all fixed
