Number * Array Gives Error

[kckennylau]

print [4]*5 produces [4, 4, 4, 4, 4] as expected, but print 5*[4] is an error.

Source diving shows that Number has undefined behaviour for a * b where b is neither a Number nor String. Source.

Y no define behavior? 😭

@schas002 NO_OP_BEHAVIOR does not mean undefined behavior
