| Subject: | ATTR chokes on whitespace |
Very simply, this works:
{
my %blob_of :ATTR( init_arg => "blob", get => "blob");
}
while this fails:
{
my %blob_of :ATTR( init_arg => "blob",
get => "blob");
}
The leading whitespace before "get =>" causes Class::Std to choke.
(The same thing happens with syntactic variants such as Perl6-style
attributes.)
Invalid HASH attribute: ( init_arg => "blob",
get => "blob") at Whatever.pm line 9
Compilation failed in require.
BEGIN failed--compilation aborted.
I'm surprised no one has reported this before. Is there something
horribly wrong with my whitespace? I doubt it, since I'm using emacs
and indent-tabs-mode set to nil. Nonetheless, I have uploaded the
precise files that cause the problem. I hope this helps with the
diagnosis.
