Hi,
Hello,
The following line stores the first return value by the function Function1 to
the variable $name:
my ($name) = @_[0] = &Function1 ($arg);
The array slice @_[0] forces list context on the right side of the
assignment but warns. $name in parentheses forces list context on the
right side of the assignment.
but this one doesn't work:
my ($name) = $_[0] = &Function1 ($arg);
The scalar value $_[0] forces scalar context on the right side of the
assignment.
Eventhough I've no issues to use the first one as long as it works well for me,
but I'm getting the following warning:
Scalar value @_[0] better written as $_[0]
When you need list context for a scalar value then enclose it in
parentheses (like you do for $name.)
my ( $name ) = ( $_[0] ) = Function1( $arg );
