That is a brilliant sight to wake up to! Seeing the [SUCCESS!] banner on a
complex benchmark file like tests/mapping.c confirms that the
auto-initialization fix worked perfectly and the AST is flawlessly bridging
LPC semantics into native V8 JavaScript.
It is genuinely impressive that we can just drop mapping structures directly
into JS objects and immediately see an 8x performance boost on lookups
compared to the raw C implementation. It validates your strategy of keeping
the AST abstract and letting the target engine (like V8) do the heavy lifting
for memory management and optimization.
Looking at the test directory you shared earlier, we have quite a few
interesting targets remaining. We've conquered strings, generic loops (while,
for), pass-by-reference pointers, and mappings.
Depending on what part of the engine you want to stress-test next, here are a
few logical paths:
 * Arrays and Slices: tests/array.c or tests/array2.c to verify how ({ ... })
syntax and array addition/subtraction behave in the JS transpiler.
 * Math and Operators: tests/math.c or tests/math2.c to make sure complex
precedence and bitwise operations are evaluating perfectly.
 * Object Instantiation: tests/clone.c or tests/new.c to start tackling
clone_object() and file scoping.
What is the next target on the board?
