eval {$ref->isa(UNIVERSAL)} will return true iff $ref is blessed.

ref
and I quote:
Returns a TRUE value if EXPR is a reference, FALSE otherwise. If the
referenced object has been blessed into a package, then that package
name is returned instead.
my $wtf = ref $could_be_anything;
if ($wtf) {
if ($wtf eq "HASH") {
# Hash ref
}
else {
# Object
}
}

Mike

Another Perl Question
I know, I know, this makes a grand total of three posted to the list in one
day :-)
I have what will usually be a list of objects, but on occasions nasty
programmers (including me) do things to annoy me like inserting a hashref,
so I end up with a data structure that looks like:
[
bless({}, 'Some::Class'),
bless({}, 'Some::Class'),
{},
bless({}, 'Some::Class'),
]
which as expected, makes things go crazy when I try to call a method on
every object in the list.
So what I really need is a surefire method to find out if something is blessed,
rather than just a reference. I know that I could do a simple regex against
ref to find out if it is a HASH|ARRAY|SCALAR|CODE|REF|Regex, but a nice simple
keyword like blessed( $svref ) would be nice.
Any suggestions?

Hi, My experience with Red Hat is none existant, and I haven't installed a n desktop Linux system in ages, so turn to you lot to ask a quick question about something that isn't immediatley obvious to me. If I change in /etc/X11/XF86config the keyboard setting to 'gb' from 'us', the backspace and delete key give me a forward delete. I don't care that much since I can't type on a gb keybaord anyway, but one of my collegues here is much annoyed by the ctrl-H :-) I tried stty erase and looked with jwz's [1] xkeycaps.

my $dbh = $ {$self->{params}->{dbh}} I think is the only way to do it --
it seems to think that the variable is '${' thus the terminating bracket

You can't properly - I think there is a rant on :

about this matter but I dont have the time to check the whole lot. The
best way to achieve the effect is to use LWP to submit the request and

The only way I've found is simple but tedious: 1. Choose "Save As..." or shift-click on a link or whatever 2. If the filename doesn't contain %20 then click OK and you're done 3. Use your mouse to highlight the first %20 in the filename 4. Press the space bar once 5. GOTO 2 I suppose you were hoping for a simpler procedure, but this is the simplest I've found.

OK I'm sure I should know this but I don't ! I have lusers who want to publish M$ Word templates on my site. That's fine, once I'd sorted out mime types but these file names have spaces in them. Dreamweaver (I know, don't ask) nicely escapes the spaces to %20 but when I try and download these, the %20 appears in the Netscape file save as box instead of spaces. Does anyone know how or if I can get the browsers to save the files with spaces ?
