=head2 Pragmatic Modules

They work somewhat like compiler directives (pragmata) in that they
tend to affect the compilation of your program, and thus will usually
work well only when used within a C<use>, or C<no>.  Most of these
are lexically scoped, so an inner BLOCK may countermand them
by saying:

    no integer;
    no strict 'refs';
    no warnings;

which lasts until the end of that BLOCK.

Some pragmas are lexically scoped--typically those that affect the
C<$^H> hints variable.  Others affect the current package instead,
like C<use vars> and C<use subs>, which allow you to predeclare a
variables or subroutines within a particular I<file> rather than
just a block.  Such declarations are effective for the entire file
for which they were declared.  You cannot rescind them with C<no
vars> or C<no subs>.

The following pragmas are defined (and have their own documentation).

=head2 Standard Modules

Standard, bundled modules are all expected to behave in a well-defined
manner with respect to namespace pollution because they use the
Exporter module.  See their own documentation for details.

It's possible that not all modules listed below are installed on your

don't have the gdbm library.
