Re^4: what does the retval of can() do ?

Ok, I see, you can call it like:

$a = A->new ;
$b = $a->can('test') ;
A->$b() if defined $b ;
$b = undef ; # de-ref

I suggest something more like: `$a->$b() if defined $b;` ... but whether your code is correct really depends on the implementation of the `test()` method. I usually see code that just checks whether `can()` returns a true value.	[reply] [d/l] [select]
