+=head1 NAME
+
+Perl::Critic::Policy::InputOutput::ProhibitOneArgSelect - Never write C<select($fh)>.
+
+=head1 AFFILIATION
+
+This Policy is part of the core L<Perl::Critic> distribution.
+
+
+=head1 DESCRIPTION
+
+Conway discourages the use of a raw C<select()> when setting
+autoflushes.  We'll extend that further by simply prohibiting the
+one-argument form of C<select()> entirely; if you really need it you
+should know when/where/why that is.  For performing autoflushes,
+Conway recommends the use of C<IO::Handle> instead.
+
+  select((select($fh), $|=1)[0]);     # not ok
+  select $fh;                         # not ok
+
+   use IO::Handle;
+   $fh->autoflush();                   # ok
+   *STDOUT->autoflush();               # ok
+
+
+=head1 CONFIGURATION
+
+This Policy is not configurable except for the standard options.
+
+
+=head1 SEE ALSO
