Wrong. Look at the following code: 
package Foo;

sub new {
    print "Right one!\n";
}

1;
--------
#!/usr/local/bin/perl

use Foo;

# Insert 1000 lines of code here

sub new {
    print "Wrong one!\n";
}

# Insert 1000 lines of code here

my $bar = new FOO;
# Compare that with my $bar = FOO->new;

By using indirect notation, you're removing the capability for the interpreter to spellcheck you if you have defined a new function in the current package. My example is contrived, but what if you're creating an object from within another object? That shows up every once in a while, right? :-)

The only reasons I can ever see to use indirect notation are the following:

  1. You're a C++ programmer that doesn't want to really learn Perl
  2. You want to do that "cool thing" in Llama3 with no parentheses on method calls.
(In case you can't tell, I find both those reasons ... lacking.)

We are the carpenters and bricklayers of the Information Age.

Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.
