But what if isa() is broken or has side effects, hmm?

That's not the caller's problem.  Fix the broken code.  Don't break more code 
trying to work around bugs.

I think the problem he's refering to is that if the caller is using eval 
{ $obj->isa(...) } you won't get an error, because it got ignored.

It will just spurious return a false result, not an exception.
