Re^5: Not understanding 2 sentences in perldoc

[LanX]

• ( ... ) = is a list assignment with list context inside the parens

  we have two nested list assignments here

•  my ($x, $y, $z) = qw( 1 2 3 ) is a list assignment

  effect $x=1, $y=2, $z=3

  returns lvalues $x, $y, $z in list context

• ( $x, $y, $z ) = qw( a b c ); is a list assignment

  effect $x="a", $y="b", $z ="c"

  doesn't return because in void context (start statement)

Hi, it's me the anonymous monk.

( $x, $y, $z ) = qw( a b c );

Why the above returns void context?

(my ($x, $y, $z) = qw( 1 2 3 )) = qw( a b c );

Does it return void context in this expression too?

[LanX]

"void context" means it returns nothing (or doesn't need to return anything)

see perlglossary

I see. But I want to know why in my ($x, $y, $z) = qw( 1 2 3 ); it's returning the lvalues in list context and why in ( $x, $y, $z ) = qw( a b c ); it's returning nothing?

And in the expression (my ($x, $y, $z) = qw( 1 2 3 )) = qw( a b c ); it's returning nothing as well?
