The monadic style of language speci cation has the advantages of modularity and extensibility: it is simple to add or change features in an interpreter to re ect modi cations in t...
There have been significant advances on formal methods to verify complex systems recently. Nevertheless, these methods have not yet been accepted as a realistic alternative to the ...
Many processes can be seen as transformations of tree-like data structures. In compiler construction, for example, we continuously manipulate trees and perform tree transformations...
In object-oriented programming, unique permissions to object references are useful for checking correctness properties such as consistency of typestate and noninterference of conc...
