This short paper presents A-TOS (Aspect-TOS (TCL Object System)), an aspect-oriented framework that allows the programmer
to define its own specialized aspects and to weave or remove them at runtime. Since A-TOS is based on a configurable and semantic-reliable
object-wrapping technique, it is able to solve what we call the Aspect-Composition Issue (ACI), i.e., to detect and solve
many semantic conflicts when weaving the different aspects together.
