Hi all,
Damian Conway's "Object Oriented Perl" has been so highly praised on this
list that I had to run out an order myself a copy. The praise is not
without merit -- it's a marvelous book (and readable too!!!).
On p. 28 of his review of the "essential Perl" he talks briefly about a
hash slice, and I who have been perling since the old perl 4 days had never
come across that capability before. But in a piece of code I'm writing
right now, I tried it out and I continueally get the following compile time
error:
Can't modify single ref constructor in scalar assignment at \
accntREQUEST.cgi line 154, near ");"
There's always more than one way to skin a cat, and I've tried several.
This is what I really want to accomplish:
my $colleague = {};
@{$colleague} = { "status",
"id",
"last_name",
"first_name",
"middle_name",
"campus",
"dob"
} = split(/:/, $record);
But, I have also tried the following, which is closer to Conway's example:
my %colleague;
@colleague{ .... } = split(/:/, $record);
And I have also created the hash and added the keys prior to attempting the
insert. I have even tried putting the split in an additional set of
parentheses on the notion that maybe I had to make the list context
explicit.
In every case, I get the error quoted above. The only thing that changes
is the offending line number, which is always the last line of the
instruction.
Does his example not work, or more likely, what am I doing wrong.
