Initialize class property with an anonymous function

by

Because it is not implemented in PHP.

http://www.php.net/manual/en/language.oop5.properties.php. Quote:

They (properties) are defined by using one of the
keywords public, protected, or
private, followed by a normal variable
declaration. This declaration may
include an initialization, but this
initialization must be a constant
value–that is, it must be able to be
evaluated at compile time and must not
depend on run-time information in
order to be evaluated.

You cannot initialize properties like this, functions are not constant values. Hence my original answer “it is not implemented”.

Why is it not implemented? That I can only guess – it probably is quite a complex task and nobody has stepped up to implement it. And/or there may not be enough demand for a feature like that.
