Perl::Critic::Policy::ValuesAndExpressions::ProhibitVersionStrings - Don't use strings like v1.4 or 1.4.5 when including other modules.


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


Whenever you use or require a module, you can specify a minimum version requirement. To ensure compatibility with older Perls, this version number should be expressed as a floating-point number. Do not use v-strings or three-part numbers. The Perl convention for expressing version numbers as floats is: version + (patch level / 1000).

    use Foo v1.2    qw(foo bar);  # not ok
    use Foo 1.2.03  qw(foo bar);  # not ok
    use Foo 1.00203 qw(foo bar);  # ok


This Policy is not configurable except for the standard options.
