Release v1.14.0 · rhaiscript/rhai

This new version contains a substantial number of bug fixes for edge cases.

A new syntax is supported to facilitate writing object methods in script.

The code hacks that attempt to optimize branch prediction performance are removed because benchmarks do not show any material speed improvements.

Bug fixes

is_shared is a reserved keyword and is now handled properly (e.g. it cannot be the target of a function pointer).
Re-optimizing an AST via optimize_ast with constants now works correctly for closures. Previously the hidden Share nodes are not removed and causes variable-not-found errors during runtime if the constants are not available in the scope.
Expressions such as (v[0].func()).prop now parse correctly.
Shadowed variable exports are now handled correctly.
Shadowed constant definitions are now optimized correctly when propagated (e.g. const X = 1; const X = 1 + 1 + 1; X now evaluates to 3 instead of 0).
Identifiers and comma's in the middle of custom syntax now register correctly.
Exporting an object map from a module with closures defined on properties now works correctly when those properties are called to mimic method calls in OOP-style.
Compiling for thumbv6m-none-eabi target (e.g. Raspberry Pi Pico) now completes successfully. Dependency to no-std-compat is now pointed to the latest repo instead of crates.io.

It is now possible to require a specific type to the this pointer for a particular script-defined function so that it is called only when the this pointer contains the specified type.
is_def_fn is extended to support checking for typed methods, with syntax is_def_fn(this_type, fn_name, arity)
Dynamic::take is added as a short-cut for std::mem::take(&mut value).

Engine::is_symbol_disabled is added to test whether a particular keyword/symbol is disabled.
Support is added to deserialize a Dynamic value containing custom types or shared values back into another Dynamic (essentially a straight cloned copy).
