I am reading thru the code in the Web::Scraper module, and don't understand how the imported subroutine named scraper is returning a Web::Scraper object.
In Web/Scraper.pm you have this
sub import {
...
*{"$pkg\::scraper"} = _build_scraper($class);
}
sub _build_scraper {
my $class = shift;
return sub(&) {
my($coderef) = @_;
bless { code => $coderef }, $class;
};
}
I get that scraper executes _build_scraper, which is a prototyped sub that takes a coderef as it's only argument. But it looks to me that calling scraper { } from the client code will return not a Web::Scraper object, but a CODEREF that, when executed, will return a Web::Scraper object using the sub{} block given to scraper{}.
If anyone can shed light on this to help me better understand what's happening that would be great.
