opposed to de-Bruijn indices). In this paper we present an extension of |
1556 | 73 |
Nominal Isabelle for dealing with general bindings, that means |
1657 | 74 |
term-constructors where multiple variables are bound at once. Such general |
75 |
bindings are ubiquitous in programming language research and only very |
|
1566 | 76 |
poorly supported with single binders, such as lambda-abstractions. Our |
77 |
extension includes novel definitions of alpha-equivalence and establishes |
|
78 |
automatically the reasoning infrastructure for alpha-equated terms. We |
|
1687 | 79 |
also prove strong induction principles that have the usual variable |
1566 | 80 |
convention already built in. |
