Michael Lazzaro asked:
OK, next question. Is _THIS_ possible?
class FileBasedHash is Hash { ...stuff... };
my %data is FileBasedHash('/tmp/foo.txt');
Yes. Though we would need a syntax for specifying that string parameter for the
generic C<FileBasedHash> class. And, of course, a mechanism for constructing the
non-generic version of the generic class from the corresponding argument.
And if _that's_ possible, is _THIS_ possible?
my $path = '/tmp/foo.txt';
my %data is FileBasedHash($path);
Indeed. In fact, there may even be a standard property that does this kind of
thing:
# Note: this is purely speculative...
my $str is from($filename); # text in file becomes chars in string
my @lines is from($filename); # lines in file become elements in array
my %config is from($filename); # colon-separated fields in file become kv pairs in hash
