For reference:
The workaround is to do this
if (is_a($a, 'B')) {
becomes
if (is_object($a) && is_a($a, 'B')) {

This also affects HTML_Template_Flexy pear package that uses is_a to check
returned object against PEAR_Error class. No matter what behavior is right it
looks broken to me because I am patching this pear packages files right now!

@stas - the point of un-depreciating and working with a string was the second
argument, not the first one.
eg.
is_a($something, 'might_be_not_loaded_class')
rather than
$something instanceof might_be_not_loaded_class

>From the manual.
"Returns TRUE if the object is of this class or has this class as one of its
parents, FALSE otherwise."
note the "FALSE otherwise" ...
Defiantly a bug..

DB_DataObject uses is_a() to check if a variable is both an object and an
instance of a particular object.
PEAR::isError() does too.
This just gives warnings in my code, and I could of course easily fix these two
places in my local pear-code. But then it will bite me the next time I upgrade
those packages from PEAR.

What code? Do you have some example?
