With regard to choosing the catch block based on the class of the exception thrown (I presume you are using something like Class::Exception or Throwable) have you considered a dispatch table? 

# this is a very crude concept example

my $val = try {
    some_operation();
}
catch {
    if ( blessed($_) ) {
        &{$exceptions_by_class{blessed($_)}}($_);
    }
    else {
        # handle normal die or croak message
        ...
    }
};

I must confess that I am a big fan of Try::Tiny and have not played with TryCatch.

Update: fixed typo in code.

You must always remember that the primary goal is to drain the swamp even when you are hip-deep in alligators.
