1.1.0

[Jeckerson]

Added

• Implemented generator (yield) support: methods containing yield; / yield expr; / yield key, value; now compile to lazy generators returning an extension-scoped <Namespace>\Generator object (\Iterator + send() + getReturn()) with PHP-identical laziness, auto-key, rewind and exhaustion semantics. Suspension works across while/loop/if/switch, for in <array> (snapshot iteration), range() and object iteration; yield inside try/catch, for ... in iterator(...), closures and functions is rejected at compile time. PHP's \Generator is final, so declare -> <\Iterator>, -> <\Traversable> or omit the return type #1849
• Added trait support: trait Name { } and import inside classes/traits. Zephir traits compile to real ZEND_ACC_TRAIT class entries, so PHP userland can use them #504

Changed

• Multi-dimensional array assignments (let a[i][j] = v) now skip a redundant final-offset hash lookup in zephir_array_update_multi_ex (three hash operations per write down to two), making tight-loop matrix builds ~15–20% faster (measured via tests/Benchmark/MultiDimArrayBench.php) #1884
• Object property reads and writes on this with a compile-time-known name now reuse a per-method interned zend_string for the name and a per-request inline property cache slot (zephir_read_property_cached / zephir_update_property_zval_cached), instead of allocating a zend_string and re-resolving the property offset by hash lookup on every access. This takes this->prop reads from ~0.44× to ~1.35× of native PHP throughput — now faster than interpreted PHP (measured via tests/Benchmark/PropertyAccessBench.php) #1902

Fixed

• Fixed arithmetic compound-assignment (+=, -=, *=) on an object property overwriting the property instead of accumulating when the right-hand side is a variable (e.g. let this->total += delta; compiled to let this->total = delta;, dropping the read). The current property value is now read, the operator applied, then written back — matching the already-correct literal-operand path. Arithmetic sibling of the concat-assign fix #2063; found while adding the property inline-cache #1902
• Pure-PHP parser parity: a closure-arrow (x => expr) now requires a bare identifier on the left, matching the C parser grammar yield "k" => 2; and let f = "x" => 2; are syntax errors again instead of being mis-parsed #1849
• for loops over the ../... range operators (for i in 0..n) now compile to an integer counting loop instead of materializing an intermediate array, matching the existing for i in range(...) optimization; this also lets a typed int loop variable be used with .., which previously failed to compile #2433
• A static property initialized with an array literal no longer breaks single-file (concatenated) builds: the zephir_init_static_properties_<Class>() initializer is now forward-declared at file scope in the project .c instead of the per-class header, keeping its declaration and definition in one translation unit so their linkage cannot mismatch (static vs non-static) #2601
