A my
declares the listed variables to be local (lexically) to the enclosing block, file, or eval
. If more than one value is listed, the list must be placed in parentheses.
The exact semantics and interface of TYPE and ATTRS are still evolving. TYPE is currently bound to the use of fields
pragma, and attributes are handled using the attributes
pragma, or starting from Perl 5.8.0 also via the Attribute::Handlers
module. See "Private Variables via my()" in perlsub for details, and fields, attributes, and Attribute::Handlers.
