I'd rather go for extra semicolon:

  • %set= map {; $_ => foo($_) } @list;
demo with perl -de0
DB<45> x map {a=>1} 1..3; # seeing hash, but co +mma missing syntax error at (eval 55)[c:/Strawberry/perl/lib/perl5db.pl:738] line +2, near "} 1" DB<46> x map {a=>1}, 1..3; # seeing hash again 0 HASH(0x2f501e8) 'a' => 1 1 HASH(0x2f4a1e8) 'a' => 1 2 HASH(0x2f4d0e0) 'a' => 1 DB<47> x map {;a=>1} 1..3; # seeing code 0 'a' 1 1 2 'a' 3 1 4 'a' 5 1 DB<48>

YMMV! :)

edit
Anyway, Perl should check for the missing comma. I suppose this happens too late for the parser.

Title:
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.
