nu-types for Effects and Freshness Analysis @INPROCEEDINGS{BDFZ09b, title = {{nu-types for Effects and Freshness Analysis}}, author = {{Massimo} {Bartoletti} and {Pierpaolo} {Degano} and {Gian Luigi} {Ferrari} and {Roberto} {Zunino}}, booktitle = {Proc. ICTAC}, pages = {80-95}, abstract = {We define a type and effect system for a $\lambda$-calculus extended with
side effects, in the form of primitives for creating and accessing resources.
The analysis correctly over-approximates the sequences of resource
accesses performed by a program at run-time.
To accurately analyse the binding between the creation of a resource and its
accesses, our system exploits a new class of types.
Our $\nu$-types have the form $\nu N.\, \tau \rhd H$, where the names in $N$
are bound both in the type $\tau$ and in the effect $H$, that represents the
sequences of resource accesses.
