if $a is a special var then @a and %a will act special too, even without carrying a meaning.

Well, they are considered "declared", but that's the extent of it.

Nope, e.g. $% is a special var which is global, @% isn't documented anywhere, but still global `DB<1> x @%=1..3 0 1 1 2 2 3 DB<2> x {package A; @%} 0 1 1 2 2 3 DB<3> x @a=1..3 # not global 0 1 1 2 2 3 DB<4> x {package A; @a} empty array DB<5>` [download] Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l]

  DB<1> x @%=1..3
0  1
1  2
2  3

  DB<2> x {package A; @%}
0  1
1  2
2  3

  DB<3> x @a=1..3  # not global
0  1
1  2
2  3

  DB<4> x {package A; @a}
  empty array

  DB<5>
