Re: Complicated Hash Construction.

[pg]

You can declare an entity, but not a member of an entity. This is what the syntax error is about. In your bad case, you tried to declare my @hash{@keyarray}, which is an element of an entity.

It is NOT about the fact that you combined a declaration with an assignment.

This is fine:

my $a = 1;

and this is not fine:

my $a[1];

This is also no good:

my @a; # this is okay
my $a[1];# no good
