NAME
    DynScalar - closure-in-a-box for simple scalars

SYNOPSIS
      use DynScalar;  # imports as dynamic()
      use strict;
      use vars '$name';
      
      my $foo = dynamic { "Hello, $name!\n" };
      for $name ("Jeff", "Joe", "Jonas") { print $foo }

DESCRIPTION
    This module creates closures, and masks them as objects that
    stringify themselves when used. This allows you to make
    incredibly simplistic string templates:

      use DynScalar 'delay';  # import as delay()
      use strict;
      use vars qw( $name $age $sex );
      
      my $template = delay {
        "Hello, $name.  You're a good-looking $age-year-old $sex.\n"
      };
      
      while (my $rec = get_person()) {
        ($name,$age,$sex) = $rec->features;
        print $template;
      }

    You can embed arbitrarily complex code in the block.

CAVEATS
    Lexically scoped variables can be used inside the block, but you
    must do so with caution. The variable must be visible, as in
    this example:

      use DynScalar;
      
      my $name;
      my $str = dynamic { $name };
      for ("Jeff", "Joe", "Jonas") { $name = $_; print $str }

    If you use the lexically scoped variable as the iterator
    variable in the loop, however, Perl will scope it even further,
    and the `DynScalar' object will not be able to see it:

      use DynScalar;
      
      my $name;
      my $str = dynamic { $name };
      # this next line will not print as you hoped
      for $name ("Jeff", "Joe", "Jonas") { print $str }
