Re^3: Sequential defined-or operators

Just be careful with precedence. Absent prototypes overriding the default,

my $value =  $hash{$arg}
          // func $arg
          // 'default';
[download]

means

my $value =  $hash{$arg}
          // func($arg // 'default');
[download]

Putting parens around the low precedence bit solves the problem.

my $value =  $hash{$arg}
          // (func $arg)
          // 'default';
[download]

Of course, with functions, you can also do

my $value =  $hash{$arg}
          // func($arg)
          // 'default';

Yes, I'm aware about this issue. I wrote related matter sometime ago. So I believe it will be perfectly fine to write: `my $value = $hash{$key} // func $arg // 'default';` [download] knowing that func is a unary operator. Open source softwares? Share and enjoy. Make profit from them if you can. Yet, share and enjoy!	[reply] [d/l]
