.SH DESCRIPTION
.IX Header "DESCRIPTION"
This package the exportable functions that many parts in
MooseX::Types might need.
.SH FUNCTIONS
.IX Header "FUNCTIONS"
.SS filter_tags
.IX Subsection "filter_tags"
Takes a list and returns two references. The first is a hash reference
containing the tags as keys and the number of their appearance as values.
The second is an array reference containing all other elements.
.SS has_available_type_export
.IX Subsection "has_available_type_export"
.Vb 1
\&  TypeConstraint | Undef = has_available_type_export($package, $name);
.Ve
.PP
This function allows you to introspect if a given type export is available
\&\fIat this point in time\fR. This means that the \f(CW$package\fR must have imported
a type constraint with the name \f(CW$name\fR, and it must be still in its symbol
table.
.PP
Two arguments are expected:
.ie n .IP $package 4
.el .IP \f(CW$package\fR 4
.IX Item "$package"
The name of the package to introspect.
.ie n .IP $name 4
.el .IP \f(CW$name\fR 4
.IX Item "$name"
The name of the type export to introspect.
.PP
\&\fBNote\fR that the \f(CW$name\fR is the \fIexported\fR name of the type, not the declared
one. This means that if you use Sub::Exporters functionality to rename an import
like this:
.PP
.Vb 1
\&  use MyTypes Str => { \-as => \*(AqMyStr\*(Aq };
.Ve
.PP
you would have to introspect this type like this:
.PP
.Vb 1
\&  has_available_type_export $package, \*(AqMyStr\*(Aq;
.Ve
.PP
The return value will be either the type constraint that belongs to the export
or an undefined value.
