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';` [download]	[reply] [d/l] [select]

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.
