I guess its important to distinguish two quite different kinds of problem:
a. Stupidity/Carelessness  ⇒  Shoot oneself in foot
b. Malice, Ill-intent, aka criminality

*** Eval error ***  Symbol's value as variable is void: k

[May or may not be obvious depending on fonts that one k is latin the other is
cyrillic ]

Now with at least aehkoptxy being present in Latin and Cyrillic,
