Re: RFC: Junction.pm

Just out of curiosity...

  if (all(5, 10, 15) > any (3, 8, 12, 20))
  {  print "Success!\n" }
[download]

Does that work? :-) Also, I'm not sure if you can override =~, but that makes much more sense in perl5 land than allowing a regex or something as a parameter, as long as you're going about all this syntactical sugar anyway:

  if (all(@input) =~ /^\d+$/) { print "Got all whole numbers!\n" }
[download]

looks much better than:

  if (all(qr/^\d+$/, @input)) { ... }
[download]

Also, these don't make a lot of sense (to me, anyway) in OO format (and I'm an OO freak!). I'd expect more like:

use Junction qw(any all);
if (any(@list) > 0) { print "we have at least one postive number!\n"; 
+}
if (all(@list) > 0) { print "even better - they're all positive number
+s!\n"; }
[download]

I'm not sure why you need that object anyway.

Agreed, exporting the subs makes a lot more sense. I originally had only the object interface, because of the way it was built - it should have occured to me to `use Exporter` once that was no longer needed. `if (all(5, 10, 15) > any (3, 8, 12, 20)) { print "Success!\n" }` [download] No, that doesn't work. I could make it work, but then it's starting to get into the complexity of Quantum::Superpositions (which I've still to fully read the docs of). Unfortunately, =~ can't be over-riden: that would be very nice. (And why Damian hasn't released Perl6::SmartMatch, I don't know ;)	[reply] [d/l] [select]

`if (all(5, 10, 15) > any (3, 8, 12, 20)) { print "Success!\n" }` [download] Yes, it does work! I should have tested before I answered: I realised that of course it would work, as the operators the module used are still overloaded, even when being used inside the module. `if (qr/^\d+$/ == all(@input)) { ... }` [download] The above now works. Note that you need to use a regex object `qr//` rather than just `//`, and you also need to use '==' or '!=', not '=~' or '!~'. It isn't ideal, but then you only need to use it if you want to! btw, I've uploaded this to CPAN as Perl6::Junction. update: changed the above link, as the cpan indexer hasn't picked it up yet, when you search by module name.
