Hi,
are the following assumptions correct?
sub foo ([EMAIL PROTECTED]) { push @args, 42 }
sub bar ([EMAIL PROTECTED] is rw) { push @args, 42 }
foo @some_array; # dies ("Can't modify constant array...")
bar @some_array;
# works, but does not change @some_array, as the * causes &bar to
# receive a *new* array (which happens to contain @some_array's
# elements), right?
# @args is only an array constructed by the parameter binding code;
# @args =:= @some_array is false (consider bar(@some_array, 42)).
bar 1,2,3; # works too
Or is @args always readonly and the declaration ([EMAIL PROTECTED] is rw) is an
error?
