Re^3: why doesn't "my ($a,$b)" return a list?

The problem stays even without prototypes.

Really? With a better prototype:

$ perl -wE 'sub list { 1, 2}; sub enum(\@@) { @_[1,2] = (1, 2)}; enum 
+my @a, state ($x, $y); say $x, $y'
12

Or with no prototype:

$ perl -wE 'sub list { 1, 2}; sub enum { @_[0,1] = (1, 2)}; enum my @a
+, state ($x, $y); say $x, $y'
12

To me this looks like the scalar context from the prototype was the problem - our maybe you meant a different problem? If so, care to elaborate?

yes sorry your right, I misintepreted the results of my tests, confusing the size of @_ with the value of the first parameter. I just realized in the meantime that this works: `DB<22> sub tst3(\@;@) {print scalar @_} DB<23> use feature 'state'; tst3 @a, state ($x,$y) 3` [download] Thanks :) Cheers Rolf	[reply] [d/l]
