------------
* Many one-liners and few-liners are now marked `#[inline]` or `[inline(always)]`, just in case it helps when LTO is not turned on.
* Default call stack depth for `debug` builds is reduced to 12 (from 16).

Limit How Stack Usage by Scripts

Rhai by default limits function calls to a maximum depth of 128 levels (16 levels in debug build).

This limit may be changed via the `Engine::set_max_call_levels` method.
