Re: Merging Arrays into a Hash with Substitutions

Taking a trick from TheDamian you could also do this:

   while ( my @row = $dbQuery->fetchrow_array() ) {
      $_ = "" for grep {not defined} @row;
      @info{@{$headings}} = @row;
   }

(I'd probably still reach for map first.)

Why have a grep and a for loop, though? `# Grep in a void context! grep { defined or $_ = '' } @row; # or defined or $_ = '' for @row;` [download]	[reply] [d/l]
