I don't mind of 'if' however it's not clear for me what to follow on other (error) branch of that 'if'.

Mostly it used in loops. So some code will be gracefully skipped and that's it.
However the case discussed is different because -1 index of an array will be accessed. Which is much
worse than a bare assertion at least.
