This is just more one limitation, not a bug. Changing to feature request.
Thanks.

"(propeties) 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."
http://www.php.net/manual/pt_BR/language.oop5.properties.php

lambda is a dynamic expression like :

function lambda() use ($variable) {
}

so, we should not allow lambda in class properties initialization.
