Perl::Critic::Policy::Objects::UseriContrPerl::Critic::Policy::Objects::ProhibitIndirectSyntax(3)

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 via static analysis.

SEE ALSO
       Perl::Critic::Policy::Dynamic::NoIndirect and indirect both do a better job with this, but
       they require that you compile/execute your code.
