摘要：Denotational semantics is a powerful technique to formally define programming
languages. However, language constructs are not always orthogonal, so many
semantic equations in a definition may have to be aware of unrelated constructs
semantics. Current approaches for modularity in this formalism do not address
this problem, providing, for this reason, tangled semantic definitions. This
paper proposes an incremental approach for denotational semantic specifications,
in which each step can either add new features or adapt existing equations, by
means of a formal language based on function transformation and aspect weaving.
