NAME

Perl::Critic::Policy::Objects::ProhibitIndirectSyntax - Prohibit indirect object call syntax.

AFFILIATION

This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

Indirect object syntax is commonly used in other object-oriented languages for instantiating objects. Perl allows this, but to say that it supports it may be going too far. Instead of writing

my $foo = new Foo;

it is preferable to write

my $foo = Foo->new;

The problem is that Perl needs to make a number of assumptions at compile time to disambiguate the first form, so it tends to be fragile and to produce hard-to-track-down bugs.

CONFIGURATION

Indirect object syntax is also hard for Perl::Critic to disambiguate, so this policy only checks certain subroutine calls. The names of the subroutines can be configured using the forbid configuration option:

[Objects::ProhibitIndirectSyntax]
forbid = create destroy

The new subroutine is configured by default; any additional forbid values are in addition to new.

CAVEATS

The general situation can not be handled.
