Re^3: 'Variable' sub names

Hi,
or so:

foreach my $product (@products) {
    &{$subs{$product}};
}
[download]

then one can see better that it is a sub call.

Keep in mind that your example will call the coderef in `$subs{$product}` with the current contents of `@_` just as if you'd called `&namedsub;`. If you want to pass an empty argument list you still need the parens: `&{ $subs{ $product } }( )`. See `perldoc perlsub` for more details.	[reply] [d/l] [select]

then one can see better that it is a sub call Perhaps one (since you count as one, I presume) can better see that, but I would think the general Perl-using population understands `$foo->()` to be a subref call. And even if I'm wrong about that, well, I just think it looks better. :-)	[reply] [d/l]
