( #3333=superdoc: print w/replies, xml ) Need Help??

It is producing a named subroutine for each name in @x. Even if somefunction() returns names which would be illegal for a sub, a function of the name will be provided.

use strict; use warnings; sub somefunction { qw/foo bar 123/ } my @x = somefunction(); for (@x) { my $foo = "${_}_func"; *{;no strict 'refs'; \*$_} = sub { $foo }; } print &123(),$/; # omitting the & sigil gives syntax error __END__ 123_func

The tight scope of no strict 'refs'; is remarkable. I've never seen it done that way. I think it is the primary advantage of doing this: stricture in in force in the sub definition. The construction seems to be equivalent to,

*{ +do { no strict 'refs'; \*$_ } } = sub { # . . . };

After Compline,

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
