It's quite impressive they're able to take nearly arbitrary C and do this! Very similar to what pypy is doing here, but for C, and not a python subset.

However not without downsides. It sounds like average code is only 2x faster than Lua, vs. LuaJit which is often 5-10x faster.

Hmm I'm wondering how hard it would be to redo the old timey Microsoft jvm from the 90s for modern days....java > .net assembly runtime

LuaJIT uses magic assembly.
