NAME

6       B::Keywords - Lists of reserved barewords and symbol names
7

SYNOPSIS

9         use B::Keywords qw( @Symbols @Barewords );
10         print join "\n", @Symbols,
11                          @Barewords;
12

DESCRIPTION

14       "B::Keywords" supplies several arrays of exportable keywords: @Scalars,
15       @Arrays, @Hashes, @Filehandles, @Symbols, @Functions, @Barewords,
16       @BarewordsExtra, @TieIOMethods, @UNIVERSALMethods and @ExporterSymbols.
17
18       The @Symbols array includes the contents of each of @Scalars, @Arrays,
19       @Hashes, @Functions and @Filehandles.
20
21       Similarly, @Barewords adds a few non-function keywords and operators to
22       the @Functions array.
23
24       @BarewordsExtra adds a few barewords which are not in keywords.h.
25
26       All additions and modifications are welcome.
27
28       The perl parser uses a static list of keywords from regen/keywords.pl
29       which constitutes the strict list of keywords @Functions and
30       @Barewords, though some @Functions are not functions in the strict
31       sense.  Several library functions use more special symbols, handles and
32       methods.
33

DATA

35       @Scalars
36       @Arrays
37       @Hashes
38       @Filehandles
39       @Functions
40           The above are lists of variables, special file handles, and built
41           in functions.
42
43       @Symbols
44           This is just the combination of all of the above: variables, file
45           handles, and functions.
46
47       @Barewords
48           This is a list of other special keywords in perl including
49           operators and all the control structures.
50
51       @BarewordsExtra
52           This is a list of barewords which are missing from keywords.h,
53           handled extra in the tokenizer.
54
55       @TieIOMethods
56           Those are special tie or PerlIO methods called by the perl core,
57           namely for tieing or PerlIO::via (or both of those) or threads.
58
59       @UNIVERSALMethods
60           Methods defined by the core package UNIVERSAL.
61
62       @ExporterSymbols
63           Variables or functions used by Exporter (some internal), which is
64           almost as good as being keywords, for you mustn't use them for any
65           other purpose in any package that isa Exporter, which is quite
66           common.
67

EXPORT

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