NAME ^

B::Keywords - Lists of reserved barewords and symbol names

SYNOPSIS ^

  use B::Keywords qw( @Symbols @Barewords );
  print join "\n", @Symbols,
                   @Barewords;

DESCRIPTION ^

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 @Functions array.

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.

DATA ^

@Scalars
@Arrays
@Hashes
@Filehandles
@Functions

The above are lists of variables, special file handles, and built in functions.

@Symbols

This is just the combination of all of the above: variables, file handles, and functions.

@Barewords

This is a list of other special keywords in perl including operators and all the control structures.

@TieIOMethods

Those are special tie or PerlIO methods called by the perl core, namely for tieing or PerlIO::via (or both of those) or threads.

@UNIVERSALMethods

Methods defined by the core package UNIVERSAL.

@ExporterSymbols

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 common.

EXPORT ^

Anything can be exported if you desire. Use the :all tag to get everything.

SEE ALSO ^

regen/keywords.pl from the perl source, perlvar, perlfunc, perldelta.
