n Perl the constructor doesn't have to be named "new" In Perl no, but OO frameworks like Moose and its derivatives have adopted this convention and use "new" for object instantiation.

Actually, constructors cannot be named `new`^†. The name of the constructor in Perl is called `bless`. ^†Unless you make an XS function called `new` which reimplements `bless`.	[reply] [d/l] [select]

I thought a constructor is any routine that calls the `bless` operator.	[reply] [d/l]

That would be a silly and confusing definition. If you had: `sub foo { my $x = bless [], "X"; my $y = bless {}, "Y"; ... return 1; }` [download] Is that a double constructor? Half a constructor?	[reply] [d/l]
