> Since the jmp is a fixed 2 bytes (0xEB, tablesize), all references to the table can still be done with trivial pc/RIP-relative addressing within the closure, and you just need one pointer for both the table and the closure data.
Only if tablesize fits in 127 bytes. Otherwise it will use 0xE9-based
encoding which is larger.
