@francois: It's not a bug. It's a feature.
It's kind of accepted that all programming languages have some keywords you
can't use as identifier names. The general solution is to just choose a
synonym. Possible alternative verbs for "unset" include:
- clear
- remove
- delete
- dispose
- drop
- erase
Unusually, the language limitation is actually fixable for "unset" because of
its obvious function-like syntax. It's probably not a priority though. Also, at
best, it would break the history of PHP syntax-coloring editors turning "unset"
keyword color.

Description:
------------
While "keywords" and "language constructs" cannot be used as function names, I
find myself with the need to have a function in my class named "unset", I also
see that list is a very common and useful term.
After the introduction of classes and namespaces it's time to look at enabling
usage of these common terms in classes and namespaces.
Test script:
---------------
<?php
namespace whatever;
class unsetTest{
function unset($whatever){
}
}
Expected result:
----------------
Happiness
Actual result:
--------------
//Parse error: syntax error, unexpected 'unset' (T_UNSET), expecting identifier
(T_STRING) in E:\_www\x.php on line #
