=over =item my EXPR X =item my TYPE EXPR =item my EXPR : ATTRS =item my TYPE EXPR : ATTRS A C declares the listed variables to be local (lexically) to the enclosing block, file, or C. 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 the C pragma, and attributes are handled using the C pragma, or starting from Perl 5.8.0 also via the C module. See L for details, and L, L, and L. =back
