DESCRIPTION

27       This library provides Moose types for checking things (mostly strings)
28       against syntax that is, or is a reasonable subset of, Perl syntax.
29

PERL VERSION

31       This library should run on perls released even a long time ago.  It
32       should work on any version of perl released in the last five years.
33
34       Although it may work on older versions of perl, no guarantee is made
35       that the minimum required version will not be increased.  The version
36       may be increased for any reason, and there is no promise that patches
37       will be accepted to lower the minimum required perl.

TYPES

40   ModuleName
41   PackageName
42       These types are identical, and expect a string that could be a package
43       or module name.  That's basically a bunch of identifiers stuck together
44       with double-colons.  One key quirk is that parts of the package name
45       after the first may begin with digits.
46
47       The use of an apostrophe as a package separator is not permitted.
48
49   DistName
50       The DistName type checks for a string like "MooseX-Types-Perl", the
51       sort of thing used to name CPAN distributions.  In general, it's like
52       the more familiar ModuleName, but with hyphens instead of double-
53       colons.
54
55       In reality, a few distribution names may not match this pattern -- most
56       famously, "CGI.pm" is the name of the distribution that contains CGI.
57       These exceptions are few and far between, and deciding what a
58       "LaxDistName" type would look like has not seemed worth it, yet.
59
60   Identifier
61       An Identifier is something that could be used as a symbol name or other
62       identifier (filehandle, directory handle, subroutine name, format name,
63       or label).  It's what you put after the sigil (dollar sign, at sign,
64       percent sign) in a variable name.  Generally, it's a bunch of
65       alphanumeric characters not starting with a digit.
66
67       Although Perl identifiers may contain non-ASCII characters in some
68       circumstances, this type does not allow it.  A "UnicodeIdentifier" type
69       may be added in the future.
70
71   SafeIdentifier
72       SafeIdentifiers are just like Identifiers, but omit the single-letter
73       variables underscore, a, and b, as these have special significance.
74
75   LaxVersionStr
76   StrictVersionStr
77       Lax and strict version strings use the is_lax and is_strict methods
78       from "version" to check if the given string would be a valid lax or
79       strict version.  version::Internals covers the details but basically:
80       lax versions are everything you may do, and strict omit many of the
81       usages best avoided.
82
83   VersionObject
84       Just for good measure, this type is included to check if a value is a
85       version object.  Coercions from LaxVersionStr (and thus
86       StrictVersionStr) are provided.
