Good find! At the moment it is very very experimental and you might experience crashes and slowdowns if you're using it in place of the regular flags (that is why it is enabled only on Nightly builds and will not be enabled on Beta/Release for a while). We'll make sure to talk about it when the right time has come.

We've had optimizations to make wasm -> JS calls fast for a long time, and they became even slightly faster (around 10 or 15%) last year. There is a proposal to add DOM integration within wasm, so one could import DOM functions in wasm and call them directly (from wasm to C++, without a "trampoline" in JS).

For what it's worth, the name is obviously a pun and a small wink to the Graal VM [1]. Not sure there's any intention to reference TempleOS's HolyC.

There's a brainfuck [1] interpreter example in the examples/ directory, which I assume is the reason for this allegedly temporary name.
