 +===== Limitations =====
 +
 +==== Overloading ====
 +Overloading of aspect constructs is not possible (right now).
 +
 +==== Type Patterns ====
 +
 +You are not allowed to use more than two meta variables or constants in type patterns.
 +
 +  call(?_ ?​package.?​type.?​m(..)) && concat("​org.cs3.",?​internal,?​package)
 +
 +is allowed
 +
 +  call(?_ org.cs3.?​internal.?​type.?​m(..)) ​
 +
 +is not allowed.
 +
 +
 +
 +==== Dynamic pointcuts ====
 +Currently dynamic pointcuts are limited the statically resolvable signatures.
 +E.g. consider the class hierarchy SubType < SuperType.
 +
 +The advice
 +  after(SubType t): target(t) && call(* *.*()) ..
 +
 +will only be woven to method calls where the target is statically known to be SubType. If only SubType is known
 +it will fail:
 +
 +  Subtype sub ..;
 +  st.m(); ​ // <- advice is woven
 +  SuperType sup = sub;
 +  sup.m(); // <- advice is not woven
 +
 +This limitation will removed in the future.
 +
 +
 +

 +**... to be completed**
