|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 is the result of the last comparison, but in superposition if for some comparision we have true the rest are not evaluated..

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