The goto statement takes a name, rather than an expression[1]. It gets
compiled as a JMP to a bytecode offset, so there's no way to use
variable labels.

$ luac -l -p - <<< 'goto label ::label::'
main <stdin:0,0> (2 instructions at 0x8cd2970)
0+ params, 2 slots, 1 upvalue, 0 locals, 0 constants, 0 functions
1 [1] JMP       0 0 ; to 2
2 [1] RETURN   0 1
