comment How does Luhn algorithm relate to cryptograpic hash functions?
That's true, but different from a one-way function. You can't recreate the original sequence of numbers. I am not suggesting Luhn is at all suitable for crypto.

A Luhn checksum certainly cannot be reversed. It definitely is a "one-way" function.

comment Save flags in an int32
Options o = (Options)i; converts from an int to the enum. If you want to convert either the enum or the int to a list of bools, there's not really a shortcut in the standard library that I know of.

comment can a logic error happen way later than its cause?
Because nothing appeared to be wrong at that point, to the user. If you define "manifest" to mean "when the bug occurred", then of course a bug can't occur earlier than it occurs..

Because it was a logic error - it loaded the data into the wrong fields. Nothing happened until later, because nobody tried to use the fields until later.

Of course. I just fixed an error in some code that loaded some data. The bug manifested later, when the data was used to calculate something.
