Re^2: Spotting an empty array as argument

> It makes it impossible to specify more than one argument, though:

I think you are confusing @ with \@ . The former will swallow the whole list


  DB<40> sub my_say (;\@$$$) { dd \@_ }

  DB<41> my_say @a
[["a1", "a2", "a3"]]

  DB<42> my_say @a,$a
[["a1", "a2", "a3"], "A"]

  DB<43> sub tst (@) { dd @_ }

  DB<44> tst @a
("a1", "a2", "a3")

  DB<45> tst @a,2
("a1", "a2", "a3", 2)

Oh, I see. I just experimented with the newer prototypes like `+` and `_` but it's still a PITA. :/ Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l] [select]
