I'd never seen the goto &LABEL
format either, so this is quite interesting. This ability to do with functions what exec
does with processes is certainly remarkable, but why
it was called "goto" is not entirely clear. Some
people, myself included, loathe that particular four letter word.
Just for the sake of clarity, it is probably best to use the return
method you suggest.
As a note, if you find this sort of thing cropping up in nine different places, maybe you should switch to an OO framework. Override the edit
method for Product::Office
which @ISA Product
my $product = new Product;
$product->edit(); # Same as edit_product
my $office_product = new Product::Office;
$office_product->edit(); # Same as edit_product_office
I've seen some very clever uses of goto
in extremely optimized code, where backing out of a pile of loops is just too costly, but this is very rare. Besides, if you were concerned about ultimate performance, you wouldn't be using Perl anyway.
