( #3333=superdoc: print w/replies, xml ) Need Help??
I've made a habit of calling functions as &FUNC(); to make them more readily visible.

The following explanations would seem to approve my approach.   Are there other factors I should take into account?   Reason(s) why I should forego the preceeding "&"?   Particular situations, perhaps?

perlman::perlsub tells me:
"& is optional with parentheses" and that "& makes current @_ visible to called subroutine".

perlman::perlvar says:
"within a subroutine the array @_ contains the parameters passed to that subroutine. See the perlsub manpage".
    thanks,

Update: After reading tye's post that Albannach linked below, and re-reading tilly's post above, I *think* I'm OK in continuing to &FUNC().

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.
