Indirect Object Syntax

In Perl, do not use: my $cgi = new Class;

Instead, always use: my $cgi = Class->new;

The section Indirect Object Syntax in the perlobj manual details why. While the indirect object syntax might appear “nice” or in the context of new “be easily distinguished from a method call,” these excuses belie the danger:

< mst> 'new Class' might invoke a method, or it might call a sub called 'new' in the current package, or it might fail to parse as a bareword, depending on the phase of the moon.
