From anno4000@lublin.zrz.tu-berlin.de

The documentation of Exporter is missing an explicit statement about
what can go into the @​EXPORT and @​EXPORT_OK arrays. Because of the
optional &-prefix for functions the rule is not obvilous and since
many modules export only (prefix-less) functions, the examples users
are likely to find may be misleading. This was discussed on clpm
under the subject "<== importing hash symbols from one package".

See patch below.

  modules and how the C<use> statement operates is important to
  understanding the Exporter.
 
+ =head2 How to Export
+
+ The arrays C<@​EXPORT> and C<@​EXPORT_OK> in a module hold lists of
+ symbols that are going to be exported into the users name space by
+ default, or which they can request to be exported, respectively. The
+ symbols can represent functions, scalars, arrays, hashes, or typeglobs.
+ The symbols must be given by full name with the exception that the
+ ampersand in front of a function is optional, e.g.
+
+ @​EXPORT = qw(sub $scalar @​array); # sub is a function
+ @​EXPORT_OK = qw(&func %hash *typeglob); # explicit prefix on &func
