B::Keywords - Lists of reserved barewords and symbol names
use B::Keywords qw( @Symbols @Barewords );
print join "\n", @Symbols,
"B::Keywords" supplies several arrays of exportable keywords:
@Scalars, @Arrays, @Hashes, @Filehandles, @Symbols, @Functions, @Barewords,
@TieIOMethods, @UNIVERSALMethods and @ExporterSymbols.
The @Symbols array includes the contents of each of @Scalars, @Arrays, @Hashes,
@Functions and @Filehandles.
Similarly, @Barewords adds a few non-function keywords and operators to the
All additions and modifications are welcome.
The perl parser uses a static list of keywords from regen/keywords.pl
which constitutes the strict list of keywords @Functions and @Barewords,
though some @Functions are not functions in the strict sense. Several library
functions use more special symbols, handles and methods.

- Those are special tie or PerlIO methods called by the perl
core, namely for tieing or PerlIO::via (or both of those) or threads.
- Methods defined by the core package UNIVERSAL.
- Variables or functions used by Exporter (some internal),
which is almost as good as being keywords, for you mustn't use them for
any other purpose in any package that isa Exporter, which is quite
Anything can be exported if you desire. Use the :all tag to get everything.
