SAFE_STACK:

if undefined, the stack will not be checked for stack overflows. This may improve

performance, however this will produce undefined behavior as you reach the stack limit (and may
|
|
cause a seg fault!). It is recommended to keep this enabled.

NAN_BOXXED:

if undefined, the interpreter will use a tagged union to store values. This is the default.

Note that even though the sizeof(CValue) is 8 bytes for NAN_BOXXED (as opposed to 16 bytes for
|
|
the tagged union) no performance benefits were measured. I recommend keeping this undefined for

now.
