- Make pattern translations total and tolerate wrapper forms to avoid Match in the bcase frontend. - Allow nested patterns in constructor args by expanding collection/translation logic in Basic_Case_Expression. - Normalize tuple patterns into Pair/TNil shape in the shallow match frontend. - Improve shallow match arg translation to distinguish bindings vs constructors and handle nested tuple patterns. - Add nested-pattern showcase/regression tests (Option/Result, tuples, wildcards, if-let and let-else forms). Closes awslabs#65. Signed-off-by: Dominic Mulligan <dominic.p.mulligan@gmail.com>
Can now use Boolean-valued pattern guards, for example:
```rust
match x with {
Some(x) if x > 0 => ...,
None => ...,
_otherwise => ...
}
```
Closes awslabs#67.

Move all tests from Micro_Rust_Shallow_Embedding.thy into a new dedicated test theory file organized by language feature category. Changes: - Create Micro_Rust_Shallow_Embedding_Tests.thy with tests organized into 21 sections covering all Micro Rust syntax features - Add missing shallow translations for compound assignment operators (-=, *=, %=, <<=, >>=) in Core_Syntax.thy and Micro_Rust_Shallow_Embedding.thy - Fix double negation (!!) parsing by adding explicit syntax rule and AST translation to expand to nested single negations - Fix double dereference (**) parsing similarly - Add tests for error propagation (?), assert_eq!/assert_ne!, signed casts (i32, i64), and all compound assignment operators - Update ROOT to include new test theory Signed-off-by: Dominic Mulligan <dominic.p.mulligan@gmail.com>
