|This is unlikely to do what you wanted. It creates a new Foo object and then
|assigns a reference to that one object to both $a and $b. It doesn't create two
|Foo objects. (But maybe one object referenced twice is what you wanted).
]- i've got it from here :
<snip apo4>
For historical reasons, the assignment in
my ($a, $b) = new Foo;
will not distribute automatically over $a and $b. If you want that, use the ^=
hyperassignment instead, maybe.

But probably i havent understood it !

|Not correct. The second case is the same as:
|
| ($x == $a, $x == $b, $x == $c)
|
|which reduces in effect to:
|
| $x == $c
]- i see now... so if ',' works the Perl5 way, then all are ecaluated but the result

]- i see, i havent read it well :
<snip apo4>
There is, however, no catch property to go with the CATCH block.
